CVE-2025-14925

Code execution via unsafe checkpoint deserialization

Published Dec 23, 2025 · Updated Dec 23, 2025

Unsafe checkpoint deserialization in Hugging Face Accelerate allows remote attackers to execute code in the current process. Checkpoint parsing fails to validate supplied data before deserializing it, allowing embedded objects to invoke code during loading. Exploitation requires the target to visit a malicious page or open a malicious checkpoint, and execution inherits the process context.
