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 to execute arbitrary system commands by providing specially crafted pickle files.
Recommendations Update to version 1.6.0 or later. As a temporary workaround, avoid using the algo from pickle() function when processing untrusted files.
