CVE-2024-12029Public exploitNetwork attack vector

Unauthenticated code execution via model deserialization

Published Mar 20, 2025 · Updated Mar 20, 2025

Unsafe model deserialization in InvokeAI 5.3.1 through 5.4.2 allows remote attackers to execute arbitrary code via the model-install API. The /api/v2/models/install path passes downloaded checkpoint files to torch.load when picklescan reports a scan error, treating only detected infected files as unsafe. No authentication or user interaction is required, and successful exploitation runs attacker-supplied Python pickle code in the InvokeAI server process.
