    PYSEC-2026-4015

    Vulnerability from pysec - Published: 2026-09-27 02:17 - Updated: 2026-10-01 08:46
    VLAI
    Details

    MONAI through 1.6.0 contains a remote code execution vulnerability in the bundle configuration engine that resolves target values to arbitrary importable callables without an allow list and passes $ expressions to Python eval(). Attackers can publish a malicious bundle with crafted configuration containing arbitrary code that executes when a victim loads the bundle using monai.bundle.load() or monai.bundle.run().
