Summary
Hugging Face Transformers fails to validate shard filenames in checkpoint index files, allowing attackers to read arbitrary files outside the model directory. Attackers can supply malicious index files with parent-directory references or absolute paths that are joined without validation, enabling file disclosure and filesystem reconnaissance.
This vulnerability allows for reading arbitrary files outside the model directory, leading to information disclosure and filesystem reconnaissance. When a user processes such a malicious checkpoint file, the path traversal vulnerability allows reading arbitrary files outside the intended model directory.
Exploitation requires local access and user interaction to process the malicious checkpoint file. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N).
Weakness: CWE-22. Affected Red Hat products: Lightspeed Core; OpenShift Lightspeed; Red Hat AI Inference Server; Red Hat Ansible Automation Platform 2; Red Hat Enterprise Linux AI (RHEL AI) 3; Red Hat OpenShift AI (RHOAI).
Red Hat does not currently list a fixing RHSA for this CVE.

Mitigation checklist
- Upgrade to a fixed version of Hugging Face Transformers when available (currently affected versions: <= 5.15.0). As a workaround, only load checkpoint files from trusted sources, implement additional validation of checkpoint index file paths before processing, and run AI/ML workloads in sandboxed environments with restricted file system access to limit the impact of arbitrary file reads.
