- Summary
- Duplicate Advisory: PickleScan's pkgutil.resolve_name has a universal blocklist bypass

Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-vvpj-8cmc-gx39. This link is maintained to preserve external references.
Original Description
picklescan before 1.0.4 fails to block pkgutil.resolve_name, allowing attackers to bypass the entire blocklist by resolving any dangerous function through indirect REDUCE calls. Remote attackers can invoke any blocked function such as os.system, builtins.exec, or subprocess.call to achieve remote code execution.
