Last modified

CVE-2026-66007 is a medium-severity vulnerability rated 6.9/10 on the CVSS scale. 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.. EPSS estimates a 0.52% chance of exploitation in the next 30 days.
