GHSA-g38g-8gr9-h9xp: PickleScan has multiple stdlib modules with direct RCE not in blocklist
(updated )
picklescan v1.0.3 (latest) does not block at least 7 Python standard library modules that provide direct arbitrary command execution or code evaluation. A malicious pickle file importing these modules is reported as having 0 issues (CLEAN scan). This enables remote code execution that bypasses picklescan entirely.
