CVE-2026-118683 Details
Description
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.
A remote code execution vulnerability exists in MONAI versions 1.2.0 prior to 1.6.1. The issue arises in the ConfigWorkflow.__init__ method, where a bundle's logging configuration file is processed without proper validation. This allows attackers to create and distribute bundles containing harmful code in the logging configuration, which is executed when the bundle is loaded or run. The vulnerability is triggered during the workflow construction phase, before any actual execution of the workflow begins.
Users are advised to update to MONAI version 1.6.1 or later, where this vulnerability has been patched.
