CVE-2025-12638: Keras path traversal in keras.utils.get_file() tar extraction

Source: NVD(opens in a new tab)
Identifier: CVE-2025-12638
Published: November 28, 2025
Record updated: October 9, 2026

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.
EPSS: 0.7%

Summary

Keras 3.11.3 contains a path traversal flaw in keras.utils.get_file() when it extracts tar archives. The function calls tarfile.extractall() without filter='data', and a PATH_MAX symlink resolution bug causes Keras's pre-extraction path filter, filter_safe_paths(), to be bypassed. Files can then be written outside the intended extraction directory, potentially leading to system compromise or malicious code execution.

Mitigation
