Doc Text:	A flaw was found in Hugging Face Diffusers. This vulnerability allows remote attackers to execute arbitrary code on affected installations. Exploitation requires user interaction, where a target must visit a malicious page or open a malicious file. The issue stems from improper validation of user-supplied data during the parsing of checkpoints, leading to deserialization of untrusted data and enabling remote code execution.	Story Points:	---

Description OSIDB Bzimport 2025-12-23 22:06:35 UTC

Hugging Face Diffusers CogView4 Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hugging Face Diffusers. 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 checkpoints. 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-27424.
