CVE-2025-14927
Description
A flaw was found in the Hugging Face Transformers library. The convert_config function fails to validate a user-supplied string before using it to execute Python code. An attacker can exploit this flaw by providing a malicious SEW-D model checkpoint, causing arbitrary code execution in the context of the user converting the file.
Statement
To exploit this issue, an attacker must convince a user to process a specially crafted SEW-D model checkpoint, limiting the possibility of exploitation. Additionally, model checkpoints are not typically processed by users with administrative privileges, limiting the potential for a full system compromise. Due to these reasons, this vulnerability has been rated with an important severity.
Mitigation
To mitigate this issue, users should avoid converting SEW-D model checkpoints from untrusted or unverified sources. Ensure that all SEW-D model checkpoints processed by the Hugging Face Transformers library originate from trusted repositories or have been verified for integrity. If that is not possible, consider processing untrusted models within an isolated sandbox environment.
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).
