What is CVE-2026-125124?
CVE-2026-125124 is a low-severity vulnerability in tmatens compose-lint, published on 10 Nov 2026.
Official description
compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. In version 0.31.0, compose-lint does not neutralize the Azure Pipelines ##vso[ logging-command opener on any output path. A pull request can place that opener in a Compose value or file name, allowing output from the package, pre-commit hook, or Docker image to issue logging commands when printed to an Azure Pipelines job log. The maintainer did not reproduce the behavior on an Azure Pipelines agent. The GitHub Action is not affected because it runs only on GitHub Actions, and releases before 0.31.0 are outside this advisory because they did not claim Azure Pipelines coverage. This issue is fixed in version 0.32.0.
