## Overview

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.

## Affected

- `MONAI >= 1.6.0 < 1.6.1`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
