| Summary | Duplicate Advisory: PickleScan has multiple stdlib modules with direct RCE not in blocklist ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-g38g-8gr9-h9xp. This link is maintained to preserve external references. ### Original Description picklescan before 1.0.4 fails to block at least seven Python standard library modules (including uuid, _osx_support, _aix_support, _pyrepl.pager, and imaplib) exposing eight functions that provide direct arbitrary command execution. Attackers can craft malicious pickle files importing these unblocked modules to achieve remote code execution while bypassing picklescan's safety validation entirely. |
