CyberRota Analysis
AI-GeneratedVersions of the PDM Python package and dependency manager up to 2.26.9 are vulnerable to arbitrary code execution due to the automatic loading of project-local plugins from an untrusted directory during initialization. This vulnerability allows attackers to execute malicious Python code with the privileges of the user running PDM, posing a significant risk in continuous integration and automation environments. Organizations using PDM, especially in contexts with elevated privileges, should prioritize upgrading to version 2.27.0 to mitigate this risk.

Original NVD Description
PDM is a Python package and dependency manager. In versions up to and including 2.26.9, PDM automatically loads project-local plugins from a .pdm-plugins directory during initialization, allowing an attacker-controlled file in an untrusted repository checkout to execute arbitrary Python code before any command is parsed. This happens because load_plugins() runs during Core.init() and adds .pdm-plugins via site.addsitedir(), which processes .pth files and immediately executes any line beginning with import, so the code runs with the privileges of the user invoking pdm and even a benign command such as pdm --version triggers it (making the impact strongest in CI, automation, and privileged contexts). The issue is fixed in version 2.27.0.
