Doc Text:	A flaw was found in the Hugging Face Transformers library. The parsing of weights fails to validate user-supplied data, causing a deserialization of untrusted data. An attacker can exploit this issue by providing a malicious GLM4 model, resulting in arbitrary code execution in the context of the current user processing the file.	Story Points:	---

Description OSIDB Bzimport 2025-12-23 22:05:52 UTC

Hugging Face Transformers GLM4 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 parsing of weights. 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 process. Was ZDI-CAN-28309.
