    CVE-2026-6859 (GCVE-0-2026-6859)

    Vulnerability from nvd – Published: 2026-04-22 13:04 – Updated: 2026-05-04 06:05
    VLAI
    Title
    Instructlab: instructlab: arbitrary code execution due to hardcoded `trust_remote_code=true`
    Summary
    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.

    Title
    Instructlab: instructlab: path traversal allows arbitrary directory creation and file write
    Summary
    A flaw was found in InstructLab. A local attacker could exploit a path traversal vulnerability in the chat session handler by manipulating the `logs_dir` parameter. This allows the attacker to create new directories and write files to arbitrary locations on the system, potentially leading to unauthorized data modification or disclosure.

    Vulnerability from cvelistv5 – Published: 2026-04-22 13:04 – Updated: 2026-05-04 06:05

    Title
    Instructlab: instructlab: arbitrary code execution due to hardcoded `trust_remote_code=true`
    Summary
    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.

    Title
    Instructlab: instructlab: path traversal allows arbitrary directory creation and file write
    Summary
    A flaw was found in InstructLab. A local attacker could exploit a path traversal vulnerability in the chat session handler by manipulating the `logs_dir` parameter. This allows the attacker to create new directories and write files to arbitrary locations on the system, potentially leading to unauthorized data modification or disclosure.
