Descriptioncompose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From version 0.30.0 until 0.32.0, the compose-lint GitHub Action prints the resolved directory from a failed sarif-file subdirectory creation without effective command suppression. Version 0.30.0 has no stop-commands window, while version 0.31.0 prints this error outside its stop-commands window. A pull request can place a committed symlink on that path to a directory whose name contains a newline followed by a workflow command, causing the SARIF-directory error to issue commands in the job log. Only the Action with sarif-file pointing into a subdirectory is affected; a workspace-root SARIF file, the compose-lint package, the pre-commit hook, and the Docker image do not expose this message. This issue is fixed in version 0.32.0.
