CVE-2026-125122

Published Nov 10, 2026 CWE-117 CWE-150

Description

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. In version 0.31.0, compose-lint does not sanitize the ##[ workflow-command opener inside strings written by --format json or --format sarif to stdout. A pull request can place that opener in a service name or other Compose value, and the GitHub Actions runner recognizes it even in the middle of a serialized line when the package, pre-commit hook, or Docker image prints JSON or SARIF to the job log. Writing the output to a file and using the compose-lint GitHub Action are not affected, and the flaw does not change the lint pass or fail result. This issue is fixed in version 0.32.0.
