CVE-2025-43847: Rvc-Project Retrieval-Based-Voice-Conversion-Webui

Critical severity, CVSS 9.8. EPSS: 1% chance of exploitation in the next 30 days.

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_path2 variable takes user input (e.g. a path to a model) and passes it to the extract_small_model 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.

Affected products

• Rvc-Project Retrieval-Based-Voice-Conversion-Webui: up to and including 2.2.231006
