SCA: security update for pdm (GHSA-78v8-vpjp-cjqh)

high Tenable Self-Hosted Container Security Plugin ID 443057

Description

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

 - pdm is a Python package and dependency manager supporting the latest PEP standards. Versions prior to
 2.27.0 are vulnerable to path traversal through write_to_fs. InstallDestination.write_to_fs() in
 src/pdm/installers/installers.py overrides the base class to add symlink/hardlink support but replaces the
 safe _path_with_destdir() (which validates via Path.resolve() + is_relative_to()) with a bare
 os.path.join() that performs no path validation. A malicious wheel with traversal entries can write
 arbitrary files. This issue has been fixed in version 2.27.0. (CVE-2026-47764)

Solution

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