CVE-2025-14928
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 HuBERT 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 HuBERT 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 HuBERT model checkpoints from untrusted or unverified sources. Ensure that all HuBERT 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).

Understanding the Weakness (CWE)
Access Control
Technical Impact: Bypass Protection Mechanism
In some cases, injectable code controls authentication; this may lead to a remote vulnerability.
Access Control
Technical Impact: Gain Privileges or Assume Identity
Injected code can access resources that the attacker is directly prevented from accessing.
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
When a product allows a user's input to contain code syntax, it might be possible for an attacker to craft the code in such a way that it will alter the intended control flow of the product. As a result, code injection can often result in the execution of arbitrary code. Code injection attacks can also lead to loss of data integrity in nearly all cases, since the control-plane data injected is always incidental to data recall or writing.
Non-Repudiation
Technical Impact: Hide Activities
Often the actions performed by injected control code are unlogged.
