Summary
MONAI has Path Traversal (Zip Slip) in NGC Private Bundle Download
Details

MONAI (Medical Open Network for AI) is an AI toolkit for health care imaging. In versions up to and including 1.5.1, a Path Traversal (Zip Slip) vulnerability exists in MONAI's _download_from_ngc_private() function. The function uses zipfile.ZipFile.extractall() without path validation, while other similar download functions in the same codebase properly use the existing safe_extract_member() function. Commit 4014c8475626f20f158921ae0cf98ed259ae4d59 fixes this issue.
