CVE-2025-43852 Details
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 model_choose variable takes user input (e.g. a path to a model) and passes it to the uvr function in vr.py. In uvr , if model_name contains the string "DeEcho", a new instance of AudioPreDeEcho class is created with the model_path attribute containing the aforementioned user input. In the AudioPreDeEcho class, the user input is used 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.
A vulnerability exists in Retrieval-Based Voice Conversion WebUI versions through 2.2.231006, allowing unsafe deserialization of user-supplied model paths. This issue arises in the 'vr.py' module, specifically within the 'AudioPreDeEcho' class. When a model path containing 'DeEcho' is provided, the application creates an instance of 'AudioPreDeEcho' with the user input as the model path. The 'torch.load' function is then used to load the model from this path, leading to unsafe deserialization and potential remote code execution.
