Summary
Microsoft APM, an open-source dependency manager for AI agents, is affected prior to 0.8.12. When it normalizes marketplace plugins, it copies components referenced in plugin.json into .apm/ without checking that the attacker-controlled agents, skills, commands, and hooks paths stay inside the plugin directory. A malicious plugin can use absolute or ../ traversal paths to copy arbitrary readable files or directories from the installer's machine during apm install.
Mitigation
Fixed in 0.8.12.
