# CVE-2025-71348: picklescan - Arbitrary Code Execution via torch.utils._config_module.load_config Bypass

Status: published. Published: 2026-06-21. Updated: 2026-11-08.

picklescan before 0.0.28 fails to detect malicious pickle files that invoke torch.utils._config_module.load_config function within reduce methods. Attackers can craft pickle files embedding arbitrary code that evades detection but executes during pickle.load, enabling remote code execution in supply chain attacks.

## Remediation

- fix: picklescan (PyPI): OSV reports a fixed version 0.0.28. Check the advisory for supported release branches. (source: OSV GHSA-vv6j-3g6g-2pvj) — https://github.com/advisories/GHSA-vv6j-3g6g-2pvj
