Deserialization RCE in Hugging Face Transformers X-CLIP Checkpoints

Executive Summary

This vulnerability is a remote code execution flaw in the Hugging Face Transformers library, specifically in the X-CLIP checkpoint conversion feature. It occurs because the software improperly validates checkpoint files during parsing, allowing deserialization of untrusted data. An attacker can exploit this by tricking a user into visiting a malicious webpage or opening a crafted file, which then lets the attacker execute arbitrary code with the same privileges as the current process.
