CVE-2026-47781: PDM is a Python package and dependency manager

Routine

HIGH 8.4

CVE-2026-47781 is a high-severity flaw (CVSS 8.4) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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 f
