CVE-2026-119578 Details
Description
MONAI from 1.6.0 before 1.6.1 contains a remote code execution vulnerability in Auto3DSeg algo_from_json() that allows attackers to run Python code via a crafted work directory's algo_object.json. Attackers can ship a malicious algorithm_templates module plus a _target_ name that is imported and instantiated when victims call AutoRunner or import_bundle_algo_history, executing code under default configuration.
A remote code execution vulnerability has been identified in MONAI versions 1.6.0 prior to 1.6.1. The issue arises in the Auto3DSeg 'algo_from_json()' function, where the application improperly handles untrusted JSON data. This vulnerability allows attackers to execute arbitrary Python code by delivering a crafted 'algo_object.json' file within a manipulated work directory. The exploitation occurs when the victim uses 'AutoRunner' or 'import_bundle_algo_history', executing the malicious code under the default configuration.
Users are advised to update to MONAI version 1.6.1 or later, where this vulnerability has been patched.
