What is CVE-2026-65010?

Hugging Face Datasets prior to version 5.00 is susceptible to a symlink-following vulnerability. This issue arises within the Extractor.extract() function, whereby local attackers can exploit predictable output paths to pre-plant symbolic links. As a result, these attackers can redirect the extraction process of archives to arbitrary locations in the filesystem. This can lead to unintended file overwriting, which poses risks of privilege escalation and potential code execution. Proper security measures and updates are essential to mitigate these risks.
