Description

Duplicate Advisory: Keras keras.utils.get_file API is vulnerable to a path traversal attack ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-hjqc-jx6g-rwp9. This link is maintained to preserve external references. ### Original Description The keras.utils.get_file API in Keras, when used with the extract=True option for tar archives, is vulnerable to a path traversal attack. The utility uses Python's tarfile.extractall function without the filter="data" feature. A remote attacker can craft a malicious tar archive containing special symlinks, which, when extracted, allows them to write arbitrary files to any location on the filesystem outside of the intended destination folder. This vulnerability is linked to the underlying Python tarfile weakness, identified as CVE-2025-4517. Note that upgrading Python to one of the versions that fix CVE-2025-4517 (e.g. Python 3.13.4) is not enough. One additionally needs to upgrade Keras to a version with the fix (Keras 3.12).

No weakness data has been published for this record.
