## 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](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#using-the-github_token-in-a-workflow)
- [The Open Source Security Foundation (OpenSSF) Security
Guide](https://github.com/ossf/scorecard/blob/main/docs/checks.md#token-permissions)
### 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.

- [GitHub Security
Guide](https://docs.github.com/en/actions/security-guides/security-hardening-for-github-actions#using-third-party-actions)
- [The Open Source Security Foundation (OpenSSF) Security
Guide](https://github.com/ossf/scorecard/blob/main/docs/checks.md#pinned-dependencies)
### Harden Runner

[Harden-Runner](https://github.com/step-security/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.

to find more details.

### 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.
