CVE-2026-125123tmatens compose-lint
NVD
Vulnerability Summary
compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. In version 0.31.0, compose-lint's argument parser writes rejected repository paths to stderr without the output sanitizer when a path is passed without a preceding -- separator. A pull request can supply a path containing workflow-command syntax; a carriage return can position that command at the start of a new line recognized by the GitHub Actions runner, allowing the package, Docker image, or a pre-commit hook with misconfigured args to issue the command in the job log. The default pre-commit configuration includes -- and is not affected, the GitHub Action is not affected, and the lint pass or fail result is unchanged. This issue is fixed in version 0.32.0.
