CVE-2026-125124— compose-lint: Text in a pull request can reach Azure Pipelines as logging commands through compose-lint 0.31.0's output

Quick assessment

Affected
tmatens compose-lint
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

compose-lint 是一款用于 Docker Compose 的安全检查工具，可在部署前识别危险配置错误。在 0.31.0 版本中，compose-lint 未在任何输出路径上对 Azure Pipelines 的 日志命令前缀进行中和处理。攻击者可通过拉取请求（Pull Request）将该前缀植入 Compose 的值或文件名中，从而使得该工具在生成包输出、执行 pre-commit 钩子或运行 Docker 镜像时，若其输出被打印到 Azure Pipelines 作业日志中，即可触发日志命令注入。维护

Vulnerability Title
compose-lint: Text in a pull request can reach Azure Pipelines as logging commands through compose-lint 0.31.0's output
Source: CVE Program / CVE List V5
Vulnerability 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.
