CVE-2024-11394Network attack vector

Code execution via unsafe Trax checkpoint deserialization

Published Nov 22, 2024 · Updated Dec 4, 2024

Deserialization in Hugging Face Transformers before 4.48.0 allows attackers to execute code through a malicious Trax model file. The Trax conversion script opens insecure checkpoint formats and deserializes their contents without validating that the objects are safe. Execution requires a user to download the crafted model and invoke the obscure conversion script, after which code runs with that user's privileges.
