CVE-2026-45539— APM – Agent Package Manager 后置链接漏洞

Microsoft APM: Symlinks under `.apm/prompts/` and `.apm/agents/` are dereferenced during `apm install`, copying host-local file contents into the project tree

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.

APM – Agent Package Manager 后置链接漏洞

APM – Agent Package Manager是Microsoft开源的一款AI代理依赖管理工具。 APM – Agent Package Manager 0.5.4版本至0.12.4版本存在后置链接漏洞，该漏洞源于Path.glob和Path.rglob调用跟随符号链接，导致远程依赖中的符号链接在集成时被解引用并写入部署目录。
