SCA: security update for pdm (GHSA-qq6c-99pv-prvf)

high Tenable Cloud Security Plugin ID 443069

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-47781)

Solution

Update the pdm library and its related packages to version 2.27.0 or later.
