Vulnerability from github – Published: 2026-10-28 21:31 – Updated: 2026-10-28 21:31

Details

MONAI from 1.2.0 before 1.6.1 contains a remote code execution vulnerability in ConfigWorkflow.init, which passes a bundle's configs/logging.conf to logging.config.fileConfig that eval()s handler class and args fields. Attackers can publish a malicious bundle whose logging.conf runs arbitrary Python at workflow construction when a victim loads or runs the bundle.
