Instructlab: instructlab: arbitrary code execution due to hardcoded `trust_remote_code=true`_CVE-2026-6859

{
    "lastseen": "",
    "description": "A flaw was found in InstructLab. The `linux_train.py` script hardcodes `trust_remote_code=True` when loading models from HuggingFace. This allows a remote attacker to achieve arbitrary Python code execution by convincing a user to run `ilab train/download/generate` with a specially crafted malicious model from the HuggingFace Hub. This vulnerability can lead to complete system compromise.",
