PYSEC-2026-2861 PDM wheel installation leads to Path Traversal via overridden write_to_fs

InstallDestination.writetofs in src/pdm/installers/installers.py overrides the base class to add symlink/hardlink support but replaces the safe pathwithdestdir which validates via Path.resolve + isrelativeto with a bare os.path.join that performs no path validation. A malicious wheel with travers...
