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

MONAI before 1.5.2 contains a deserialization of untrusted data vulnerability in the algofrompickle 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 algofrompickle ...

CVE-2026-100846

The MONAI library, in versions prior to 1.5.2 , is vulnerable to Remote Code Execution (RCE) due to an insecure deserialization of untrusted data. The flaw exists within the algo_from_pickle function located in monai/auto3dseg/utils.py , which processes .pkl files and passes their contents to pic...

PT-2026-99463

Name of the Vulnerable Software and Affected Versions MONAI versions prior to 1.6.0 Description Remote code execution is possible through the algo from pickle function in monai/auto3dseg/utils.py. The issue stems from the unsafe use of pickle.loads during deserialization, which allows attackers t...

PT-2026-83382

Summary GHSA-89gg-p5r5-q6r4 claims the pickle deserialization vulnerability in algo from pickle was fixed in v1.5.2. However, monai/auto3dseg/utils.py has not been modified since 2024-07-12 — 18 months before v1.5.2 was released 2026-01-29. All three pickle.loads calls remain unchanged. The fix w...

MONAI: Unsafe functions lead to pickle deserialization rce

Summary The algofrompickle function in monai/auto3dseg/utils.py causes pickle.loadsdatabytes to be executed, and it does not perform any validation on the input parameters. This ultimately leads to insecure deserialization and can result in code execution vulnerabilities. Details poc import pickl...
