Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
InstructLab versions up to and including 0.26.1 are affected. A remote attacker can achieve arbitrary Python code execution if a user is convinced to run ilab train, download, or generate with a specially crafted malicious model from the HuggingFace Hub, which can lead to full system compromise. No fix is listed in the source. Users should avoid loading untrusted models with these commands.
