CVE-2026-63766
GPT-SoVITS up to version 20250606v2pro contains a critical OS command injection flaw. Unsanitized user input is passed directly to shell commands in the web UI, allowing attackers to run arbitrary commands on the server without authentication. The vulnerability is exploitable remotely and can compromise the entire host.
No official fix yet. If none appears within 45 days of first tracking, this entry is removed automatically.
Who is affected
All installations of GPT-SoVITS version 20250606v2pro or earlier that expose the webui.py interface, especially the ASR, slice, denoise, and uvr5 endpoints.
Real-world impact
An attacker could execute any operating‑system command on the machine running GPT‑SoVITS, potentially taking full control of the server, stealing data, or installing malware.
Why this severity
The CVSS score of 9.3 reflects the high confidentiality, integrity, and availability impact (all high) combined with the fact that the flaw is remotely exploitable with no authentication or privileges required. The vector shows a local shell execution with no mitigations, leading to a critical rating.
