Detailsinfo

A vulnerability was found in RVC-Project Retrieval-based-Voice-Conversion-WebUI up to 2.2.231006. It has been rated as very critical. This issue affects the function change_info of the file process_ckpt.py. The manipulation of the argument ckpt_path0 with an unknown input leads to a deserialization vulnerability. Using CWE to declare the problem leads to CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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_path0 variable takes user input (e.g. a path to a model) and passes it to the change_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 at securitylab.github.com. The identification of this vulnerability is CVE-2025-43848 since 04/17/2025. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/01/2025).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
