CVE-2026-66007 (GCVE-0-2026-66007)

Vulnerability from cvelistv5 – Published: 2026-07-24 14:58 – Updated: 2026-07-25 10:30 X_Open Source

Title

Datasets Path Traversal via Unsanitized file_name Metadata

Summary

Datasets through 5.0.0, fixed in commit f989ef9, contains a path traversal vulnerability in folder-based dataset builders where the file_name metadata field is not properly validated before being joined to the dataset directory. Attackers can supply crafted file_name values with directory traversal sequences to read arbitrary local files, which are then embedded into output when save_to_disk or push_to_hub is called.

Severity

6.9 (Medium)

Vulnerability from github – Published: 2026-07-24 15:33 – Updated: 2026-07-24 15:33

Details

Datasets through 5.0.0, fixed in f989ef9, contains a path traversal vulnerability in folder-based dataset builders where the file_name metadata field is not properly validated before being joined to the dataset directory. Attackers can supply crafted file_name values with directory traversal sequences to read arbitrary local files, which are then embedded into output when save_to_disk or push_to_hub is called.
