CVE-2025-43843: Rvc-Project Retrieval-Based-Voice-Conversion-Webui

Critical severity, CVSS 9.8. EPSS: 2.4% 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 command injection. The variables exp_dir1, np7 and f0method8 take user input and pass it into the extract_f0_feature function, which concatenates them into a command that is run on the server. This can lead to arbitrary command execution. As of time of publication, no known patches exist.
