Duplicate Advisory: Remote Code Execution via Malicious Pickle File Bypassing Static Analysis

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-655q-fx9r-782v. This link is maintained to preserve external references.

Original Description

picklescan before 0.0.21 does not treat 'pip' as an unsafe global. An attacker could craft a malicious model that uses Pickle to pull in a malicious PyPI package (hosted, for example, on pypi.org or GitHub) via pip.main(). Because pip is not a restricted global, the model, when scanned with picklescan, would pass security checks and appear to be safe, when it could instead prove to be problematic.
