CVE-2026-65010Public exploit

Arbitrary file write via surviving extraction symlink

Published Jul 23, 2026 · Updated Jul 23, 2026

Symlink following in Hugging Face Datasets 5.0.0 and earlier allows local users to write arbitrary files during archive extraction. Extractor.extract() silently ignores shutil.rmtree() failing on a symlinked output path, then format-specific extractors follow that surviving link and unpack archive members into its target. Exploitation requires write access to a predictable shared-cache path and a victim extraction, allowing sensitive-file overwrite with the victim process's privileges.
