CVE-2026-65010
Description
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).
Statement
Datasets is vulnerable to symlink following during archive extraction in Extractor.extract(). A local attacker with low privileges who can pre-plant symlinks at predictable output paths, and who can induce extraction (user interaction), may overwrite arbitrary filesystem locations. Fixed after Datasets 5.00 (commit ad2d853).
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality,Integrity,Access Control
Technical Impact: Read Files or Directories; Modify Files or Directories; Bypass Protection Mechanism
An attacker may be able to traverse the file system to unintended locations and read or overwrite the contents of unexpected files. If the files are used for a security mechanism then an attacker may be able to bypass the mechanism.
Other
Technical Impact: Execute Unauthorized Code or Commands
Windows simple shortcuts, sometimes referred to as soft links, can be exploited remotely since a ".LNK" file can be uploaded like a normal file. This can enable remote execution.
