Summary
Duplicate Advisory: Picklescan (scan_pytorch) Bypass via dynamic eval MAGIC_NUMBER
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-97f8-7cmv-76j2. This link is maintained to preserve external references.

Original Description

picklescan before 1.0.3 contains a scanning bypass vulnerability in the scan_pytorch function that allows attackers to embed malicious magic numbers via dynamic eval using the reduce trick. Attackers can craft malicious PyTorch payloads that evade picklescan detection while remaining executable, enabling arbitrary code execution when loaded with torch.load().
