Summary
Microsoft APM, an open-source dependency manager for AI agents, is affected by CVE-2026-46383 in versions prior to 0.13.0. On supported Python 3.10 and 3.11 runtimes on Windows, the legacy-bundle probe used by apm install <bundle> calls raw tar.extractall() on untrusted tar members without rejecting Windows absolute member names such as D:/.... The flaw is reached when a local .tar.gz that is not a plugin-format bundle is passed to apm install.
