What is CVE-2026-65701?
CVE-2026-65701 is a critical path traversal vulnerability in svc-develop-team so-vits-svc, published on 23 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-22
