Summary

Duplicate Advisory: Picklescan Bypasses Unsafe Globals Check using pty.spawn

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-hgrh-qx5j-jfwx. This link is maintained to preserve external references.

Original Description

PickleScan before 0.0.33 fails to include the pty.spawn function in its unsafe globals list, allowing attackers to bypass security checks. Malicious actors can craft pickle payloads using pty.spawn to achieve arbitrary code execution when files are processed by PickleScan.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
