HTTP Client uses incorrect token after refresh

Moderate
josephdecock published GHSA-7mr7-4f54-vcx5 Nov 7, 2024

Package

nuget Duende.AccessTokenManagement.OpenIdConnect (NuGet)

Affected versions

3.0.0

Patched versions

3.0.1

Description

Impact

HTTP Clients created by AddUserAccessTokenHttpClient may use a different user's access token after a token refresh. This occurs because a refreshed token will be captured in pooled HttpClient instances, which may be used by a different user.

Workarounds

Instead of using AddUserAccessTokenHttpClient to create an HttpClient that automatically adds a managed token to outgoing requests, you can use the HttpConext.GetUserAccessTokenAsync extension method or the IUserTokenManagementService.GetAccessTokenAsync method.

Patches

This issue is fixed in Duende.AccessTokenManagement.OpenIdConnect 3.0.1.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
