Summary

Retrieval-based-Voice-Conversion-WebUI, a voice changing framework based on VITS, is vulnerable to unsafe deserialization in versions 2.2.231006 and prior. The ckpt_a and cpkt_b variables accept user-supplied model paths that the merge function in process_ckpt.py loads with torch.load, which can lead to remote code execution. The source lists the weakness as CWE-502 and assigns a CVSS 4.0 vector with network attack vector, low complexity, no privileges and no user interaction.

Mitigation
