A vulnerability in keras-team/keras version 3.12.0 allows an attacker to craft a malicious tar archive that bypasses the "filter_safe_tarinfos" validation in "keras/src/utils/file_utils.py". Specifically, symlink entries are not subjected to the same "is_path_in_dir" validation as regular file entries, allowing symlinks to be created outside the intended extraction directory. This can lead to symlink-based file read, file overwrite, or directory escape attacks. The issue is particularly impactful on Python 3.10 and 3.11, where "filter_safe_tarinfos" is the sole defense against tar path traversal. This vulnerability is distinct from CVE-2025-12060 and other previously reported issues.
