CVE-2026-47781 (opens in a new tab)How to fix?
Upgrade Debian:14 pdm to version 2.27.0-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream pdm package and not the pdm package as distributed by Debian.
See How to fix? for Debian:14 relevant fixed versions and status.
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.
