Attackers can craft pickle files embedding arbitrary code that evades detection but executes during pickle.load, enabling remote code execution in supply chain attacks.

Affected products

picklescan: before 0.0.28 — fixed in 0.0.28

How to fix

Upgrade to a fixed version: picklescan 0.0.28. Check the vendor advisory for mitigations.
