Free GitHub Action brings security scanning to Shell, Dockerfile, Terraform, and PHP
On July 14, 2026, GitHub added AI-powered security detections for Shell/Bash, Dockerfiles, Terraform, and PHP on pull requests, but restricted the feature to paid GitHub Advanced Security subscribers. Since CodeQL's free tier does not cover any of these four file types, many infrastructure-focused repositories have had no free scanning option. A developer has released an open-source GitHub Action called ghas-free-pack that runs ShellCheck, Hadolint, tfsec, and PHPStan against the respective file types and consolidates findings into a single SARIF report. The results are uploaded to GitHub's Security tab and posted as a grouped PR comment, mirroring the experience of paid CodeQL results. The action is MIT-licensed, supports Linux runners, and ships with a test harness validating 17 acceptance criteria.
