Doc Text:	A flaw was found in Hugging Face Datasets through 5.00 in Extractor.extract(). When archive contents are extracted to predictable output paths, the extractor follows pre-planted symlinks instead of confining writes to the intended directory. A local attacker who can place those symlinks can redirect extraction and overwrite arbitrary files, impacting integrity and availability (including possible privilege escalation or code execution in shared-cache setups).

Description OSIDB Bzimport 2026-07-23 19:01:29 UTC

Datasets through 5.00, fixed in commit ad2d853, contains a symlink-following vulnerability in Extractor.extract() that allows local attackers to write arbitrary files by pre-planting symlinks at predictable output paths. Attackers can redirect archive extraction to arbitrary filesystem locations in shared-cache environments, enabling overwrite of sensitive files and potential privilege escalation or code execution.
