What it is

SoftVC VITS Singing Voice Conversion through commit 730930d contains a path traversal vulnerability in the full-song inference server that allows unauthenticated remote attackers to read and exfiltrate arbitrary files by supplying attacker-controlled filesystem paths through the audio_path field of an unauthenticated POST request to the /wav2wav route. Attackers can pass arbitrary server-side paths verbatim to librosa.load, torchaudio.load, and soundfile.write sinks, causing the server to decode and return file contents via the HTTP response body while also writing attacker-specified .wav files to arbitrary locations on the filesystem.
