Exploited in the last 30 days

Logto is the modern, open-source auth infrastructure for SaaS and AI apps. From 1.40.1 until 1.41.0, Logto's .github/workflows/commitlint.yml directly interpolated github.event.pull_request.title into the Commitlint on PR title step's inline echo command before piping the title to npx commitlint. A pull request title containing a single quote could terminate the echo string and append arbitrary shell commands on the GitHub Actions runner. The pull_request trigger used a read-only GITHUB_TOKEN and did not expose repository secrets, but injected commands could alter or disrupt the ephemeral workflow execution. This issue is fixed in version 1.41.0.
