CVE-2025-1889

Mmaitre314 Picklescan vulnerability

9.8 CRITICALPublic exploitEPSS 0.40%
  1. Published3 Mar 2025

Description

picklescan before 0.0.22 only considers standard pickle file extensions in the scope for its vulnerability scan. An attacker could craft a malicious model that uses Pickle and include a malicious pickle file with a non-standard file extension. Because the malicious pickle file inclusion is not considered as part of the scope of picklescan, the file would pass security checks and appear to be safe, when it could instead prove to be problematic.
