Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-84r2-jw7c-4r5q. This link is maintained to preserve external references.

Original Description

picklescan before 0.0.33 contains an incomplete deny-list that fails to block pydoc.locate and operator.methodcaller functions, allowing attackers to bypass security checks. Remote attackers can craft malicious pickle files using these unblocked functions to achieve arbitrary code execution when the pickle is deserialized.
