CVE-2025-14922

Code execution via untrusted checkpoint deserialization

Published Dec 23, 2025 · Updated Dec 23, 2025

Deserialization in Hugging Face Diffusers CogView4 allows remote attackers to execute arbitrary code through a crafted checkpoint file. The CogView4 checkpoint parser reconstructs objects from user-supplied checkpoint data without first validating that the serialized content is trusted. Exploitation requires a target to visit a malicious page or open a malicious file, after which code runs with the privileges of the current process.
