## Description

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.
