Teleport 8.0 is a major release of Teleport that contains new features, improvements, and bug fixes.
Teleport 8.0 includes a preview of the Windows Desktop Access feature, allowing users passwordless login to Windows Desktops via any modern web browser.
Teleport users can connect to Active Directory enrolled Windows hosts running Windows 10, Windows Server 2012 R2 and newer Windows versions.
To try this feature yourself, check out our Getting Started Guide.
Review the Desktop Access design in:
In TLS routing mode all client connections are wrapped in TLS and multiplexed on a single Teleport proxy port.
TLS routing can be enabled by including the following auth service configuration:
auth_service:
proxy_listener_mode: multiplex
...and setting proxy configuration version to v2 to prevent legacy listeners from
being created:
version: v2
proxy_service:
...Teleport application access extends AWS console support to CLI . Users are able
to log into their AWS console using tsh app login and use tsh aws commands
to interact with AWS APIs.
See more info in the documentation.
With dynamic registration users are able to manage applications and databases without needing to update static YAML configuration or restart application or database agents.
See dynamic registration guides for apps and databases.
With RDS auto discovery Teleport database agents can automatically discover RDS instances and Aurora clusters in an AWS account.
See updated RDS guide for more information.
WebAuthn support enables Teleport users to use modern second factor options, including Apple FaceID and TouchID.
In addition, the Teleport Web UI includes new second factor management tools, enabling users to configure and update their second factor devices via their web browser.
Lastly, our UI becomes more secure by requiring an additional second factor confirmation for certain privileged actions (editing roles for second factor confirmation, for example).
- Added support for CockroachDB to Database Access. #8505
- Reduced network utilization on large clusters during login. #8471
- Added metrics and added the ability for
tctl topto show network utilization for resource propagation. #8338 #8603 #8491 - Added support for account recovery and cancellation. #6769

- Fixed issue where JWT signer was omitted from bootstrap logic. #8119
CentOS 6 support will be deprecated in Teleport 8 and removed in Teleport 9.
Teleport 8 will continue to receive security patches for about 9 months after which it will be EOL. Users are encouraged to upgrade to CentOS 7 in that time frame.
New run time dependencies have been added to Teleport 8 due to the inclusion of
Rust in the build chain. Teleport 8 requires libgcc_s.so and libm.so be
installed on systems running Teleport.
Users of distroless container images are encouraged to use the gcr.io/distroless/cc-debian11 image to run Teleport.
FROM gcr.io/distroless/cc-debian11
Alpine users are recommended to install the libgcc package in addition to any
glibc compatibility layer they have already been using.
apk --update --no-cache add libgcc
With the GODEBUG=x509ignoreCN=0 flag removed in Go 1.17, Database Access users
will no longer be able to connect to databases that include their hostname in
the CommonName field of the presented certificate. Users are recommended to
update their database certificates to include hostname in the
Subject Alternative Name extension instead.
Subscribe to Github issue #7636 which will add ability to control level of TLS verification as a workaround.
New clusters will no longer have the default admin role, it has been replaced
with 3 smaller scoped roles: access, auditor, and editor.
Teleport 7.0 is a major release of Teleport that contains new features, improvements, and bug fixes.
Added support for MongoDB to Teleport Database Access. #6600.
View the Database Access with MongoDB for more details.

View the Cloud SQL MySQL guide for more details.
Added support for AWS Console to Teleport Application Access. #7590
Teleport Application Access can now automatically sign users into the AWS Management Console using Identity federation. View AWS Management Console guide for more details.
Added the ability to block network traffic (IPv4 and IPv6) on a per-SSH session basis. Implemented using BPF tooling which required kernel 5.8 or above. #7099
Updated Enhanced Session Recording to no longer require the installation of external compilers like bcc-tools. Implemented using BPF tooling which required kernel 5.8 or above. #6027
- Added the ability to terminate Database Access certificates when the certificate expires. #5476
- Added additional FedRAMP compliance controls, such as custom disconnect and MOTD messages. #6091 #7396
- Added the ability to export Audit Log and session recordings using the Teleport API. #6731 #7360
- Added the ability to partially configure a cluster. #5857 RFD #28
- Added the ability to disable port forwarding on a per-host basis. #6989

tsh config. #7437 - Added default-port detection to
tsh#6374 - Improved performance of the Web UI for users with many roles. #7588
- Fixed a memory leak that could affect etcd users. #7631
- Fixed an issue where
tsh logincould fail if the user had multiple public addresses defined on the proxy. #7368
Enhanced Session Recording has been updated to use CO-RE BPF executables. This makes deployment much simpler, you no longer have to install bcc-tools, but comes with a higher minimum kernel version of 5.8 and above. #6027
Kubernetes Access will no longer automatically register a cluster named after the Teleport cluster if the proxy is running within a Kubernetes cluster. Users wishing to retain this functionality now have to explicitly set kube_cluster_name. #6786
tsh login has been updated to no longer change the current Kubernetes context. While tsh login will write credentials to kubeconfig it will only update your context if tsh login --kube-cluster or tsh kube login <kubeCluster> is used. #6045
Teleport 6.2 contains new features, improvements, and bug fixes.
Note: the DynamoDB migration described below may cause rate-limiting errors from AWS APIs and is slow on large deployments (1000+ existing audit events). The next patch release, v6.2.1, will improve the migration performance. If you run a large DynamoDB-based cluster, we advise you to wait for v6.2.1 before upgrading.
Added support for Amazon Redshift to Teleport Database Access.#6479.
View the Database Access with Redshift on AWS Guide for more details.

kubectl execsessions were not being recorded when the target pod was killed. #6068 - Fixed an issue that prevented Teleport from starting on ARMv7 systems. #6711.
- Fixed issue that caused Access Requests to inconsistently allow elevated Kuberentes access. #6492
- Fixed an issue that could cause
session.endevents not to be emitted. #6756 - Fixed an issue with PAM variable interpolation. #6558
Teleport 6.2 brings a potentially backward incompatible change with tsh agent forwarding.
Prior to Teleport 6.2, tsh ssh -A would create an in-memory SSH agent from your ~/.tsh directory and forward that agent to the target host.
Starting in Teleport 6.2 tsh ssh -A by default now forwards your system SSH agent (available at $SSH_AUTH_SOCK). Users wishing to retain the prior behavior can use tsh ssh -o "ForwardAgent local".
For more details see RFD 22 and implementation in #6525.
DynamoDB users should note that the events backend indexing strategy has changed and a data migration will be triggered after upgrade. For optimal performance perform this migration with only one auth server online. It may take some time and progress will be periodically written to the auth server log. During this migration, only events that have been migrated will appear in the Web UI. After completion, all events will be available.
For more details see RFD 24 and implementation in #6583.
This release of Teleport contains multiple bug fixes.

Teleport 6.0 is a major release with new features, functionality, and bug fixes.
We have implemented Database Access, open sourced role-based access control (RBAC), and added official API and a Go client library.
Users can review the 6.0 milestone on Github for more details.
Review the Database Access design in RFD #11.
With Database Access users can connect to PostgreSQL and MySQL databases using short-lived certificates, configure SSO authentication and role-based access controls for databases, and capture SQL query activity in the audit log.
Configure Database Access following the Getting Started guide.
To learn more about configuring role-based access control for Database Access, check out RBAC section.
Architecture provides a more in-depth look at Database Access internals such as networking and security.
See Reference for an overview of Database Access related configuration and CLI commands.
Finally, check out Frequently Asked Questions.
Open source RBAC support was introduced in RFD #7.
RBAC support gives OSS administrators more granular access controls to servers and other resources with a cluster (like session recording access). An example of an RBAC policy could be: "admins can do anything, developers must never touch production servers and interns can only SSH into staging servers as guests"
In addition, some Access Workflow Plugins will now become available to open source users.
- Access Workflows Golang SDK and API
- Slack
- Gitlab
- Mattermost
- JIRA Plugin
- PagerDuty Plugin
API and Client Libraries support was introduced in RFD #10.
The new API and client library reduces the dependencies needed to use the Teleport API as well as making it easier to use. An example of using the new API is below.
// Create a client connected to the Auth server with an exported identity file.
clt, err := client.NewClient(client.Config{
Addrs: []string{"auth.example.com:3025"},
Credentials: []client.Credentials{
client.LoadIdentityFile("identity.pem"),
},
})
if err != nil {
log.Fatalf("Failed to create client: %v.", err)
}
defer clt.Close()
// Create a Access Request.
accessRequest, err := types.NewAccessRequest(uuid.New(), "access-admin", "admin")
if err != nil {
log.Fatalf("Failed to build access request: %v.", err)
}
if err = clt.CreateAccessRequest(ctx, accessRequest); err != nil {
log.Fatalf("Failed to create access request: %v.", err)
}- Added
utmp/wtmpsupport for SSH in #5491. - Added the ability to set a Kubernetes specific public address in #5611.
- Added Proxy Protocol support to Kubernetes Access in #5299.
- Added ACME (Let's Encrypt) support to make getting and using TLS certificates easier. #5177.
- Added the ability to manage local users to the Web UI in #2945.
- Added the ability to preserve timestamps when using
tsh scpin #2889.
- Fixed authentication failure when logging in via CLI with Access Workflows after removing
.tshdirectory in #5323. - Fixed
tsh loginfailure when--proxydiffers from actual proxy public address in #5380. - Fixed session playback issues in #2945.
- Fixed several UX issues in #5559, #5568, #4965, and #5057.
Please follow our standard upgrade procedure to upgrade your cluster.
Note, for clusters using GitHub SSO and Trusted Clusters, when upgrading SSO users will lose connectivity to leaf clusters. Local users will not be affected.
To restore connectivity to leaf clusters for SSO users, leaf admins should update the trusted_cluster role mapping resource like below.
kind: trusted_cluster
version: v2
metadata:
name: "zztop-oss"
spec:
enabled: true
token: "bar"
web_proxy_addr: 172.10.1.1:3080
tunnel_addr: 172.10.1.1:3024
role_map:
- remote: "admin"
local: ['admin']
- remote: "^(github-.*)$"
local: ['admin']This release of Teleport adds a new feature.
- Support for creating and assuming Access Workflow requests from within the Web UI (first step toward full Workflow UI support: #4937).
This release of Teleport contains a security fix.
- Patch a SAML authentication bypass (see https://github.com/russellhaering/gosaml2/security/advisories/GHSA-xhqq-x44f-9fgg): #5119.
Any Enterprise SSO users using Okta, Active Directory, OneLogin or custom SAML connectors should upgrade their auth servers to version 5.0.2 and restart Teleport. If you are unable to upgrade immediately, we suggest disabling SAML connectors for all clusters until the updates can be applied.
This release of Teleport contains multiple bug fixes.
- Always set expiry times on server resource in heartbeats #5008
- Fixes streaming k8s responses (
kubectl logs -f,kubectl run -it, etc) #5009 - Multiple fixes for the k8s forwarder #5038
Teleport 5.0 is a major release with new features, functionality, and bug fixes. Users can review 5.0 closed issues on Github for details of all items.
Teleport 5.0 introduces two distinct features: Teleport Application Access and significant Kubernetes Access improvements - multi-cluster support.
Teleport can now be used to provide secure access to web applications. This new feature was built with the express intention of securing internal apps which might have once lived on a VPN or had a simple authorization and authentication mechanism with little to no audit trail. Application Access works with everything from dashboards to single page Javascript applications (SPA).
Application Access uses mutually authenticated reverse tunnels to establish a secure connection with the Teleport unified Access Plane which can then becomes the single ingress point for all traffic to an internal application.
Adding an application follows the same UX as adding SSH servers or Kubernetes clusters, starting with creating a static or dynamic invite token.
$ tctl tokens add --type=appThen simply start Teleport with a few new flags.
$ teleport start --roles=app --token=xyz --auth-server=proxy.example.com:3080 \
--app-name="example-app" \
--app-uri="http://localhost:8080"This command will start an app server that proxies the application "example-app" running at http://localhost:8080 at the public address https://example-app.example.com.
Applications can also be configured using the new app_service section in teleport.yaml.
app_service:
# Teleport Application Access is enabled.
enabled: yes
# We've added a default sample app that will check
# that Teleport Application Access is working
# and output JWT tokens.
# https://dumper.teleport.example.com:3080/
debug_app: true
apps:
# Application Access can be used to proxy any HTTP endpoint.
# Note: Name can't include any spaces and should be DNS-compatible A-Za-z0-9-._
- name: "internal-dashboard"
uri: "http://10.0.1.27:8000"
# By default Teleport will make this application
# available on a sub-domain of your Teleport proxy's hostname
# internal-dashboard.teleport.example.com
# - thus the importance of setting up wilcard DNS.
# If you want, it's possible to set up a custom public url.
# DNS records should point to the proxy server.
# internal-dashboard.teleport.example.com
# Example Public URL for the internal-dashboard app.
# public_addr: "internal-dashboard.acme.com"
# Optional labels
# Labels can be combined with RBAC rules to provide access.
labels:
customer: "acme"
env: "production"
# Optional dynamic labels
commands:
- name: "os"
command: ["/usr/bin/uname"]
period: "5s"
# A proxy can support multiple applications. Application Access
# can also be deployed with a Teleport node.
- name: "arris"
uri: "http://localhost:3001"
public_addr: "arris.example.com"Application access requires two additional changes. DNS must be updated to point the application domain to the proxy and the proxy must be loaded with a TLS certificate for the domain. Wildcard DNS and TLS certificates can be used to simplify deployment.
# When adding the app_service certificates are required to provide a TLS
# connection. The certificates are managed by the proxy_service
proxy_service:
# We've extended support for https certs. Teleport can now load multiple
# TLS certificates. In the below example we've obtained a wildcard cert
# that'll be used for proxying the applications.
# The correct certificate is selected based on the hostname in the HTTPS
# request using SNI.
https_keypairs:
- key_file: /etc/letsencrypt/live/teleport.example.com/privkey.pem
cert_file: /etc/letsencrypt/live/teleport.example.com/fullchain.pem
- key_file: /etc/letsencrypt/live/*.teleport.example.com/privkey.pem
cert_file: /etc/letsencrypt/live/*.teleport.example.com/fullchain.pemYou can learn more at https://goteleport.com/teleport/docs/application-access/
Teleport 5.0 also introduces two highly requested features for Kubernetes.
- The ability to connect multiple Kubernetes Clusters to the Teleport Access Plane, greatly reducing operational complexity.
- Complete Kubernetes audit log capture #4526, going beyond the existing
kubectl execcapture.
For a full overview please review the Kubernetes RFD.
To support these changes, we've introduced a new service. This moves Teleport Kubernetes configuration from the proxy_service into its own dedicated kubernetes_service section.
When adding the new Kubernetes service, a new type of join token is required.
tctl tokens add --type=kubeExample configuration for the new kubernetes_service:
# ...
kubernetes_service:
enabled: yes
listen_addr: 0.0.0.0:3027
kubeconfig_file: /secrets/kubeconfigNote: a Kubernetes port still needs to be configured in the proxy_service via kube_listen_addr.
tsh kube commands are used to query registered clusters and switch kubeconfig context:
$ tsh login --proxy=proxy.example.com --user=awly
# list all registered clusters
$ tsh kube ls
Cluster Name Status
------------- ------
a.k8s.example.com online
b.k8s.example.com online
c.k8s.example.com online
# on login, kubeconfig is pointed at the first cluster (alphabetically)
$ kubectl config current-context
proxy.example.com-a.k8s.example.com
# but all clusters are populated as contexts
$ kubectl config get-contexts
CURRENT NAME CLUSTER AUTHINFO
* proxy.example.com-a.k8s.example.com proxy.example.com proxy.example.com-a.k8s.example.com
proxy.example.com-b.k8s.example.com proxy.example.com proxy.example.com-b.k8s.example.com
proxy.example.com-c.k8s.example.com proxy.example.com proxy.example.com-c.k8s.example.com
# switch between different clusters:
$ tsh kube login c.k8s.example.com
# the traditional way is also supported:
$ kubectl config use-context proxy.example.com-c.k8s.example.com
# check current cluster
$ kubectl config current-context
proxy.example.com-c.k8s.example.comOther Kubernetes changes:
- Support k8s clusters behind firewall/NAT using a single Teleport cluster #3667
- Support multiple k8s clusters with a single Teleport proxy instance #3952
We've added two new RBAC resources; these provide the ability to limit token creation and to list and modify Teleport users:
- resources: [user]
verbs: [list,create,read,update,delete]
- resources: [token]
verbs: [list,create,read,update,delete]Learn more about Teleport's RBAC Resources
Teleport 5.0 also adds the ability to set labels on Trusted Clusters. The labels are set when creating a trusted cluster invite token. This lets teams use the same RBAC controls used on nodes to approve or deny access to clusters. This can be especially useful for MSPs that connect hundreds of customers' clusters - when combined with Access Workflows, cluster access can easily be delegated. Learn more by reviewing our Truster Cluster Setup & RBAC Docs
Creating a trusted cluster join token for a production environment:
$ tctl tokens add --type=trusted_cluster --labels=env=prodkind: role
#...
deny:
# cluster labels control what clusters user can connect to. The wildcard ('*')
# means any cluster. By default, deny rules are empty to preserve backwards
# compatibility
cluster_labels:
'env': 'prod'Teleport 5.0 also iterates on the UI Refresh from 4.3. We've moved the cluster list into our sidebar and have added an Application launcher. For customers moving from 4.4 to 5.0, you'll notice that we have moved session recordings back to their own dedicated section.
Other updates:
- We now provide local user management via
https://[cluster-url]/web/users, providing the ability to easily edit, reset and delete local users. - Teleport Node & App Install scripts. This is currently an Enterprise-only feature that provides customers with an easy 'auto-magic' installer script. Enterprise customers can enable this feature by modifying the 'token' resource. See note above.
- We've added a Waiting Room for customers using Access Workflows. Docs
Starting with Teleport 5.0, we now provide an RPM repo for stable releases of Teleport. We've also started signing our RPMs to provide assurance that you're always using an official build of Teleport.
See https://rpm.releases.teleport.dev/ for more details.
- Added
--format=jsonplayback option fortsh play. For exampletsh play --format=json ~/play/0c0b81ed-91a9-4a2a-8d7c-7495891a6ca0.tar | jq '.eventcan be used to show all events within an a local archive. #4578 - Added support for continuous backups and auto scaling for DynamoDB. #4780
- Added a Linux ARM64/ARMv8 (64-bit) Release. #3383
- Added
https_keypairsfield which replaceshttps_key_fileandhttps_cert_file. This allows administrators to load multiple HTTPS certs for Teleport Application Access. Teleport 5.0 is backwards compatible with the old format, but we recommend updating your configuration to usehttps_keypairs.
Enterprise Only:
tctlcan load credentials from~/.tsh#4678- Teams can require a user submitted reason when using Access Workflows #4573
- Updated
tctlto always format resources as lists in JSON/YAML. #4281 - Updated

- Added automatic arm64 builds of Teleport to the download portal.
This release of Teleport contains a bug fix.
- Fixed an issue where defining multiple logging configurations would cause Teleport to crash. #4598
This is a major Teleport release with a focus on new features, functionality, and bug fixes. It’s a substantial release and users can review 4.4 closed issues on Github for details of all items.
This addition to Teleport helps customers obtain AC-10 control. We now provide two new optional configuration values: max_connections and max_sessions.
This value is the total number of concurrent sessions within a cluster to nodes running Teleport. This value is applied at a per user level. If you set max_connections to 1, a tsh user would only be able to tsh ssh into one node at a time.
This value limits the total number of session channels which can be established across a single SSH connection (typically used for interactive terminals or remote exec operations). This is for cases where nodes have Teleport set up, but a user is using OpenSSH to connect to them. It is essentially equivalent to the MaxSessions configuration value accepted by sshd.
spec:
options:
# Optional: Required to be set for AC-10 Compliance
max_connections: 2
# Optional: To match OpenSSH behavior set to 10
max_sessions: 10A new session_control_timeout configuration value has been added to the auth_service configuration block of the Teleport config file. It's unlikely that you'll need to modify this.
auth_service:
session_control_timeout: 2m # default
# ...Teleport 4.4 includes a complete refactoring of our event system. This resolved a few customer bug reports such as #3800: Events overwritten in DynamoDB and #3182: Teleport consuming all disk space with multipart uploads.
Along with foundational improvements, 4.4 includes two new experimental session_recording options: node-sync and proxy-sync.
NOTE: These experimental modes require all Teleport auth servers, proxy servers and nodes to be running Teleport 4.4.
# This section configures the 'auth service':
auth_service:
# Optional setting for configuring session recording. Possible values are:
# "node" : sessions will be recorded on the node level (the default)
# "proxy" : recording on the proxy level, see "recording proxy mode" section.
# "off" : session recording is turned off
#
# EXPERIMENTAL *-sync modes: proxy and node send logs directly to S3 or other
# storage without storing the records on disk at all. This mode will kill a
# connection if network connectivity is lost.
# NOTE: These experimental modes require all Teleport auth servers, proxy servers and
# nodes to be running Teleport 4.4.
#
# "node-sync" : sessions recording will be streamed from node -> auth -> storage
# "proxy-sync : sessions recording will be streamed from proxy -> auth -> storage

A vulnerability was discovered in the github.com/russellhaering/goxmldsig library which is used by Teleport to validate the
signatures of XML files used to configure SAML 2.0 connectors. With a carefully crafted XML file, an attacker can completely
bypass XML signature validation and pass off an altered file as a signed one.
The goxmldsig library has been updated upstream and Teleport 4.3.7 includes the fix. Any Enterprise SSO users using Okta,
Active Directory, OneLogin or custom SAML connectors should upgrade their auth servers to version 4.3.7 and restart Teleport.

This is a major Teleport release with a focus on new features, functionality, and bug fixes. It’s a substantial release and users can review 4.3 closed issues on Github for details of all items. We would love your feedback - please pick a time slot for a remote UX feedback session if you’re interested.
Teleport 4.3 includes a completely redesigned Web UI. The new Web UI expands the management functionality of a Teleport cluster and the user experience of using Teleport to make it easier and simpler to use. Teleport's new terminal provides a quick jumping-off point to access nodes and nodes on other clusters via the web.
Teleport's Web UI now exposes Teleport’s Audit log, letting auditors and administrators view Teleport access events, SSH events, recording session, and enhanced session recording all in one view.
Teleport 4.3 introduces four new plugins that work out of the box with Approval Workflow. These plugins allow you to automatically support role escalation with commonly used third party services. The built-in plugins are listed below.
- Added the ability for local users to reset their own passwords. #2387
- Added user impersonation (
kube_users)support to Kubernetes Proxy. #3369 - Added support for third party S3-compatible storage for sessions. #3057
- Added support for GCP backend data stores. #3766 #3014
- Added support for X11 forwarding to OpenSSH servers. #3401
- Added support for auth plugins in proxy
kubeconfig. #3655 - Added support for OpenSSH-like escape sequence. #3752
- Added
--browserflag totsh. #3737 - Updated

tshandgpg-agentintegration. #3169 - Fixed Vulnerabilities in Teleport Docker Image https://quay.io/repository/gravitational/teleport?tab=tags
Always follow the recommended upgrade procedure to upgrade to this version.
If you’re upgrading an existing version of Teleport, you may want to consider rotating CA to SHA-256 or SHA-512 for RSA SSH certificate signatures. The previous default was SHA-1, which is now considered to be weak against brute-force attacks. SHA-1 certificate signatures are also no longer accepted by OpenSSH versions 8.2 and above. All new Teleport clusters will default to SHA-512 based signatures. To upgrade an existing cluster, set the following in your teleport.yaml:
teleport:
ca_signature_algo: "rsa-sha2-512"
Rotate the cluster CA, following these docs.
Due to the number of changes included in the redesigned Web UI, some URLs and functionality have shifted. Refer to the following ticket for more details. #3580
Teleport 4.3 has made the audit log accessible via the Web UI. Enterprise customers
can limit access by changing the options on the new event resource.
# list and read audit log, including audit events and recorded sessions
- resources: [event]
verbs: [list, read]The minimum set of Kubernetes permissions that need to be granted to Teleport proxies has been updated. If you use the Kubernetes integration, please make sure that the ClusterRole used by the proxy has sufficient permissions.
The etcd backend now correctly uses the “prefix” config value when storing data. Upgrading from 4.2 to 4.3 will migrate the data as needed at startup. Make sure you follow our Teleport upgrade guidance.
Note: If you use an etcd backend with a non-default prefix and need to downgrade from 4.3 to 4.2, you should backup Teleport data and restore it into the downgraded cluster.
This release of Teleport contains a security fix.
- Mitigated CVE-2020-15216 by updating github.com/russellhaering/goxmldsig.
A vulnerability was discovered in the github.com/russellhaering/goxmldsig library which is used by Teleport to validate the
signatures of XML files used to configure SAML 2.0 connectors. With a carefully crafted XML file, an attacker can completely
bypass XML signature validation and pass off an altered file as a signed one.
The goxmldsig library has been updated upstream and Teleport 4.2.12 includes the fix. Any Enterprise SSO users using Okta,
Active Directory, OneLogin or custom SAML connectors should upgrade their auth servers to version 4.2.12 and restart Teleport.
If you are unable to upgrade immediately, we suggest deleting SAML connectors for all clusters until the updates can be applied.

As part of a routine security audit of Teleport, a security vulnerability was discovered that affects all recent releases of Teleport. We strongly suggest upgrading to the latest patched release to mitigate this vulnerability.
Due to a flaw in how the Teleport Web UI handled host certificate validation, host certificate validation was disabled for clusters where connections were terminated at the node. This means that an attacker could impersonate a Teleport node without detection when connecting through the Web UI.
Clusters where sessions were terminated at the proxy (recording proxy mode) are not affected.
Command line programs like tsh (or ssh) are not affected by this vulnerability.
To mitigate this issue, upgrade and restart all Teleport proxy processes.

This is a major Teleport release which introduces support for Teleport Internet of Things (IoT). In addition to this new feature this release includes usability, performance, and bug fixes listed below.
With Teleport 4.0, nodes gain the ability to use reverse tunnels to dial back to a Teleport cluster to bypass firewall restrictions. This allows connections even to nodes that a cluster does not have direct network access to. Customers that have been using Trusted Clusters to achieve this can now utilize a unified interface to access all nodes within their infrastructure.
With this release of Teleport, we have built out the foundation to help Teleport Enterprise customers build and meet the requirements in a FedRAMP System Security Plan (SSP). This includes a FIPS 140-2 friendly build of Teleport Enterprise as well as a variety of improvements to aid in complying with security controls even in FedRAMP High environments.
- Teleport now support 10,000 remote connections to a single Teleport cluster. Using our recommend hardware setup.
- Added ability to delete node using
tctl rm. #2685 - Output of
tsh lsis now sorted by node name. #2534
- Switched to
xdg-opento open a browser window on Linux. #2536 - Increased SSO callback timeout to 180 seconds. #2533
- Set permissions on TTY similar to OpenSSH. #2508
The lists of improvements and bug fixes above mention only the significant changes, please take a look at the complete list on Github for more.
Teleport 4.0 is backwards compatible with Teleport 3.2 and later. Follow the recommended upgrade procedure to upgrade to this version.
Note that due to substantial changes between Teleport 3.2 and 4.0, we recommend creating a backup of the backend datastore (DynamoDB, etcd, or dir) before upgrading a cluster to Teleport 4.0 to allow downgrades.
Teleport has always validated host certificates when a client connects to a server, however prior to Teleport 4.0, Teleport did not validate the host the user requests a connection to is in the list of principals on the certificate. To ensure a seamless upgrade, make sure the hosts you connect to have the appropriate address set in public_addr in teleport.yaml before upgrading.

This vulnerability only affects authenticated clients, there is no known way to exploit this vulnerability outside the cluster for unauthenticated clients.
- Upgraded Go to 1.11.4 to mitigate CVE-2018-16875: CPU denial of service in chain validation Go.
This release of Teleport contains the following bug fix:
- Fix regression that marked ADFS claims as invalid. #2293

- Rollback to Go 1.9.7 for users with custom CA running into
x509: certificate signed by unknown authority.
The primary goal of 2.7.0 release was to address the community feedback and improve the performance and flexibility when running Teleport clusters with large number of nodes.
- The Web UI now includes
scp(secure copy) functionality. This allows Windows users and other users of the Web UI to upload/download files into SSH nodes using a web browser. - Fine-grained control over forceful session termination has been added #1935. It is now possible to:
- Forcefully disconnect idle clients (no client activity) after a specified timeout.
- Forcefully disconnect clients when their certificates expire in the middle of an active SSH session.
- Performance of SSH login commands have been improved on large clusters (thousands of nodes). #2061
- DynamoDB storage back-end performance has been improved. #2021
- Performance of session recording via a proxy has been improved #1966
- Connections between trusted clusters are managed better #2023
As awlays, this release contains several bug fixes. The full list can be seen here. Here are some notable ones:
- It is now possible to issue certificates with a long TTL via admin's
auth signtool. Previously they were limited to 30 hours for undocumented reason. 1745 - Dynamic label values were shown as empty strings. 2056

- The new CLI command
tsh statusshows users which Teleport clusters they are authenticated with. #1628
Additionally, Teleport 2.6.0 has been submitted to the AWS marketplace. Soon AWS users will be able to create properly configured, secure and highly available Teleport clusters with ease.
-
Role templates (depreciated in Teleport 2.3) were fully removed. We recommend migrating to role variables which are documented here
-
Resource names (like roles, connectors, trusted clusters) can no longer contain unicode or other special characters. Update the names of all user created resources to only include characters, hyphens, and dots.
-
advertise_iphas been deprecated and replaced withpublic_addrsetting. See #1803 The existing configuration files will still work, but we advise Teleport administrators to update it to reflect the new format. -
Teleport no longer uses
boltdbback-end for storing cluster state by default. The new default is calleddirand it uses simple JSON files stored in/var/lib/teleport/backend. This change applies to brand new Teleport installations, the existing clusters will continue to useboltdb. -
The default set of enabled cryptographic primitives has been updated to reflect the latest state of SSH and TLS security. #1856.

This is a major release of Teleport. Its goal is to make cloud-native deployments easier. Numerous AWS users have contributed feedback to this release, which includes:
-
Auth servers in highly available (HA) configuration can share the same
/var/lib/teleportdata directory when it's hosted on NFS (or AWS EFS). #1351 -
There is now an AWS reference deployment in
examples/awsdirectory. It uses Terraform and demonstrates how to deploy large Teleport clusters on AWS using best practices like auto-scaling groups, security groups, secrets management, load balancers, etc. -
The Teleport daemon now implements built-in connection draining which allows zero-downtime upgrades. See documentation.
-
Dynamic join tokens for new nodes can now be explicitly set via
tctl node add --token. This allows Teleport admins to use an external mechanism for generating cluster invitation tokens. #1615 -
Teleport now correctly manages certificates for accessing proxies behind a load balancer with the same domain name. The new configuration parameter
public_addrmust be used for this. #1174.
-
Switching to a new TLS-based auth server API improves performance of large clusters. #1528
-
Session recordings are now compressed by default using gzip. This reduces storage requirements by up to 80% in our real-world tests. #1579
-
More user-friendly authentication errors in Teleport audit log helps Teleport admins troubleshoot configuration errors when integrating with SAML/OIDC providers. #1554, #1553, #1599
-
tshclient will now report if a server's API is no longer compatible.
-
tsh logoutwill now correctly log out from all active Teleport sessions. This is useful for users who're connected to multiple Teleport clusters at the same time. #1541 -
When parsing YAML, Teleport now supports
--list item separator to create multiple resources with a singletctl createcommand. #1663 -
Fixed a panic in the Web UI backend #1558
Certain components of Teleport behave differently in version 2.5. It is important to note that these changes are not breaking Teleport functionality. They improve Teleport behavior on large clusters deployed on highly dynamic cloud environments such as AWS. This includes:
- Session list in the Web UI is now limited to 1,000 sessions.
- The audit log and recorded session storage has been moved from
/var/lib/teleport/logto/var/lib/teleport/log/<auth-server-id>. This is related to #1351 described above. - When connecting a trusted cluster users can no longer pick an arbitrary name for them.
Their own (local) names will be used, i.e. the
cluster_namesetting now defines how the cluster is seen from the outside. #1543
This release of Teleport contains a bugfix.
- Only reset SIGINT handler if it has not been set to ignore. #1814
