What this means

MONAI versions 1.6.0 before 1.6.1 contain a vulnerability in Auto3DSeg algo_from_json() that may allow attackers to execute code via a crafted work directory's algo_object.json. Attackers can ship a malicious algorithm_templates module to execute code under default configuration.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

Read the full publisher 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.
