Vulnerability Title
picklescan - Scanning Bypass via Dynamic Eval in scan_pytorch
Source: CVE Program / CVE List V5
Vulnerability 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().
