Doc Text:
A flaw was found in Hugging Face PyTorch Image Models. A remote attacker could exploit a deserialization of untrusted data vulnerability by enticing a user to visit a malicious page or open a malicious file. This could lead to arbitrary code execution in the context of the current process. The flaw exists due to insufficient validation of user-supplied data during the parsing of checkpoints.

Description OSIDB Bzimport 2026-08-20 16:56:04 UTC 
Hugging Face PyTorch Image Models checkpoint Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hugging Face PyTorch Image Models. 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-27987.
