Applio is a voice conversion tool. Versions 3.2.8-bugfix and prior are vulnerable to unsafe deserialization in inference.py. "model_file" in inference.py as well as "model_file" in tts.py take user-supplied input (e.g. a path to a model) and pass that value to the "change_choices" and later to "get_speakers_id" function, which loads that model with "torch.load" in inference.py (line 326 in 3.2.8-bugfix), which is vulnerable to unsafe deserialization. The issue can lead to remote code execution. A patch is available on the "main" branch of the repository.
