CVE-2026-12482Network attack vector

File read and overwrite via unchecked symlink names

Published Jul 14, 2026 · Updated Jul 14, 2026

Path traversal in Keras 3.12.0 allows attackers to read or overwrite files outside the extraction directory via a crafted tar archive. In keras/src/utils/file_utils.py, filter_safe_tarinfos checks a symlink target but never validates the symlink entry's own name with is_path_in_dir, so extraction can create the link beyond the intended destination. A user or consuming application must process the attacker-supplied archive; on Python 3.10 and 3.11 this Keras filter is the sole traversal defense.
