CVE-2025-43848
Apache Retrieval-based-Voice-Conversion-WebUI Remote Code Execution
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_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.

CVSS Scores
The Common Vulnerability Scoring System is a standardized framework for assessing the severity of vulnerabilities in software and systems. We collect and displays CVSS scores from various sources for each CVE.
Score Version Severity Vector Exploitability Score Impact Score Source
CVSS 3.1 CRITICAL [email protected]
CVSS 4.0 HIGH [email protected]
Solution
Avoid loading untrusted models by validating model paths and using secure loading mechanisms.
  • Update the framework to the latest version when available.
  • Validate all model paths before loading.
  • Implement secure deserialization practices.
  • Avoid loading models from untrusted sources.
