Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The datasets package before 5.0.1 has a path traversal flaw in folder-based builders, where the file_name metadata field is not validated before joining to the dataset directory. An attacker supplying crafted file_name values can read arbitrary local files, embedding them in output on save_to_disk or push_to_hub. Upgrade to 5.0.1.
