Critical CVSS 9.8

Overview

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 , a new instance of AudioPre class is created with the model_path attribute containing the aformentioned user input. In the AudioPre 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.

Risk analysis

This vulnerability is rated 🔴 CRITICAL.

  • CVSS: 9.8 (CRITICAL)
  • Detected tags: deserialization, rce (tag impact: VERY HIGH)

Recommended actions:

  • Avoid untrusted deserialization; prefer safe formats (JSON) and signatures.
  • Patch/upgrade immediately (remote code execution).
  • Reduce exposure (WAF/segmentation), minimize attack surface.
