Detailsinfo

A vulnerability, which was classified as problematic, has been found in tmatens compose-lint up to 0.31.x. Affected by this issue is an unknown code of the component SARIF file Handler. The manipulation with an unknown input leads to a link following vulnerability. Using CWE to declare the problem leads to CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. Impacted is integrity, and availability. CVE summarizes:

compose-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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-125125 since 11/09/2026. The exploitation is known to be easy. The attack may be launched remotely. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available.

Upgrading to version 0.32.0 eliminates this vulnerability.
