What is CVE-2024-11394?
CVE-2024-11394 is a high-severity unsafe deserialization vulnerability in Hugging Face Transformers, published on 22 Nov 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
Hugging Face Transformers Trax Model Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hugging Face Transformers. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of model files. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-25012.
Weakness: CWE-502
