Detailsinfo

A vulnerability was found in RVC-Project Retrieval-based-Voice-Conversion-WebUI up to 2.2.231006. It has been declared as very critical. This vulnerability affects an unknown part of the file process_ckpt.py. The manipulation of the argument ckpt_path1 with an unknown input leads to a deserialization vulnerability. The CWE definition for the vulnerability is CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Retrieval-based-Voice-Conversion-WebUI is a voice changing framework based on VITS. Versions 2.2.231006 and prior are vulnerable to unsafe deserialization. The ckpt_path1 variable takes user input (e.g. a path to a model) and passes it to the show_info function in process_ckpt.py, which uses it to load the model on that path with torch.load, which can lead to unsafe deserialization and remote code execution. As of time of publication, no known patches exist.

The advisory is shared for download at securitylab.github.com. This vulnerability was named CVE-2025-43846 since 04/17/2025. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 08/01/2025).
