GHSL-2025-012_Retrieval-based-Voice-Conversion-WebUI

8.9 High

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, trainset_dir4 and sr2 take user input and pass it to the preprocess_dataset 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.
