CVE-2026-100846 · MONAI before 1.5.2 Remote Code Execution via Pickle Deserialization

This page contains facts from public vulnerability sources. Check the original advisory before updating.

MONAI before 1.5.2 contains a deserialization of untrusted data vulnerability in the algo_from_pickle function in monai/auto3dseg/utils.py. The function reads a .pkl file and passes its contents to pickle.loads without validating the data source or content. If an application invokes algo_from_pickle on an attacker-supplied pickle file, an object defining __reduce__ is executed during deserialization, resulting in arbitrary code execution in the context of the application.
