Which versions of Picklescan are affected by EUVD-2025-210417?

Picklescan versions before 0.0.29 fail to detect a new class of malicious pickle files that execute arbitrary code upon deserialization, exposing organizations that rely on picklescan to validate…. A patch is available.

How to fix or mitigate EUVD-2025-210417?

Within 24 hours: Identify all systems running picklescan and inventory ML/AI pipelines accepting untrusted pickle-format model artifacts. Within 7 days: Upgrade picklescan to version 0.0.29 or later, immediately re-scan any previously-validated model repositories with the patched version, and restrict acceptance of pickle files from external sources. Within 30 days: Implement model artifact signing/verification, establish periodic security audits of model sources, and transition to safer serialization formats where feasible.

picklescan before 0.0.29 fails to detect malicious pickle files using idlelib.calltip.get_entity function in reduce methods. Attackers can embed undetected code in pickle files that executes remote commands when loaded by victims.

AnalysisAI

Security-control bypass in picklescan before 0.0.29 lets attackers craft malicious pickle files that evade its malware scanner by hiding a reduce-method payload behind Python's idlelib.calltip.get_entity function, so a file the scanner reports as clean executes arbitrary commands when a victim deserializes it. Affected are ML/AI pipelines and users relying on picklescan to vet untrusted model artifacts. No public exploit or CISA KEV listing is identified at time of analysis, though the technique and a GitHub Security Advisory (GHSA-9xph-j2h6-g47v) are documented by VulnCheck.
