A path traversal vulnerability has been identified in the Fishaudio Bert-VITS2 application, specifically within the Model Handler component's function '_get_all_models' in the file 'hiyoriUI.py'. This vulnerability allows unauthenticated remote attackers to traverse directories, probe for file existence, and read arbitrary '.wav' files. The application, which uses FastAPI, exposes these vulnerabilities over the network without any authentication. The issue has been verified on the latest commit, and the vendor has not responded to disclosure attempts.
