Security Fixes

Least Privileged GitHub Actions Token Permissions

The GITHUB_TOKEN is an automatically generated secret to make authenticated calls to the GitHub API. GitHub recommends setting minimum token permissions for the GITHUB_TOKEN.

• GitHub Security Guide
• The Open Source Security Foundation (OpenSSF) Security Guide

Pinned Dependencies

GitHub Action tags and Docker tags are mutable. This poses a security risk. GitHub's Security Hardening guide recommends pinning actions to full length commit.

Harden Runner

Harden-Runner is an open-source security agent for the GitHub-hosted runner to prevent software supply chain attacks. It prevents exfiltration of credentials, detects tampering of source code during build, and enables running jobs without sudo access.

Keeping your actions up to date with Dependabot

With Dependabot version updates, when Dependabot identifies an outdated dependency, it raises a pull request to update the manifest to the latest version of the dependency. This is recommended by GitHub as well as The Open Source Security Foundation (OpenSSF).

Add Dependency Review Workflow

The Dependency Review Workflow enforces dependency reviews on your pull requests. The action scans for vulnerable versions of dependencies introduced by package version changes in pull requests, and warns you about the associated security vulnerabilities. This gives you better visibility of what's changing in a pull request, and helps prevent vulnerabilities being added to your repository.

• Github Guide about Dependency Review
• Github Guide for Configuring Dependency Review Action

Add OpenSSF Scorecard Workflow

OpenSSF Scorecard is an automated tool that assesses a number of important heuristics ("checks") associated with software security and assigns each check a score of 0-10. You can use these scores to understand specific areas to improve in order to strengthen the security posture of your project.

Scorecard workflow also allows maintainers to display a Scorecard badge on their repository to show off their hard work.
