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.

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. See how popular open-source projects use Harden-Runner here.

Maintain Code Quality with Pre-Commit

Pre-commit is a framework for managing and maintaining multi-language pre-commit hooks. Hooks can be any scripts, code, or binaries that run at any stage of the git workflow. Pre-commit hooks are useful for enforcing code quality, code formatting, and detecting security vulnerabilities.

Pull request overview

This PR applies security hardening updates across the repo’s GitHub Actions workflows (pinning action refs and adding runner hardening) and introduces a pre-commit configuration intended to improve local developer hygiene.

Changes:

• Pin several GitHub Actions dependencies to commit SHAs instead of mutable refs/tags.
• Add a new .pre-commit-config.yaml with gitleaks + formatting/lint hooks.
