2DescriptionNVD
Microsoft APM is an open-source, community-driven dependency manager for AI agents. From 0.5.4 to 0.12.4, two primitive integrators in apm-cli enumerate package files with bare Path.glob() / Path.rglob() calls and read each match with Path.read_text(), transparently following symbolic links. A symlink committed inside a remote APM dependency under .apm/prompts/<x>.prompt.md or .apm/agents/<x>.agent.md is preserved verbatim into apm_modules/ on clone and then dereferenced during integration, with the resolved content written as a regular file into the project's deploy directories. The package content_hash, the pre-deploy SecurityGate scan, and apm audit do not flag this. The deploy roots are not added to the auto-generated .gitignore, so the resulting files are staged by git add by default. This vulnerability is fixed in 0.13.0.
AnalysisAI
Symbolic link following vulnerability in Microsoft APM dependency manager versions 0.5.4 to 0.12.4 allows remote attackers to read arbitrary files from the victim's system through malicious dependencies. The vulnerability occurs when APM processes symlinks in remote dependencies, following them to read local files and potentially exposing sensitive data that gets staged in git repositories. …

RemediationAI
Within 24 hours: Identify all systems running Microsoft APM versions 0.5.4-0.12.4 and isolate them from external dependency repositories; disable automatic dependency updates. Within 7 days: Audit git repositories and local file access logs for evidence of unauthorized symlink traversal; rotate credentials for any accounts with access to compromised systems. …
