Keras versions prior to 3.12.3 and some earlier versions contain a vulnerability in tar archive extraction that allows symlink-based path traversal. The flaw arises because symlink entries in tar archives bypass the path validation that regular files undergo, enabling attackers to create symlinks outside the intended extraction directory. This can lead to unauthorized file reads, overwrites, or directory escapes. The issue is particularly relevant for Python 3.10 and 3.11 environments where the vulnerable function is the primary defense against such attacks. The vulnerability has a low severity score and a patch is available.

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.
