CVE-2025-43850 Information

Description

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_dir variable takes user input (e.g. a path to a model) and passes it to the change_info function in export.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.
