pdm: pdm is a Python package and dependency manager supporting the latest PEP standards
CVE-2026-47764 is fixed in 2 products on 1 platform, first by OPENSUSE-SU-2026:21161-1, released June 26, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
