AI-suggested
Immediate mitigation should focus on restricting access to the GPT-SoVITS-WebUI to trusted users and networks only, employing network segmentation and firewall rules to limit exposure. Administrators should disable or restrict the functionality that allows user-supplied model paths until a patch is available. Implementing input validation and sanitization on the model_choose parameter can reduce risk, although this is a temporary measure. Monitoring and logging all access to the vulnerable component is critical to detect potential exploitation attempts. Organizations should also consider running the application in a sandboxed or containerized environment with minimal privileges to contain any compromise. Finally, staying alert for vendor updates or patches and applying them promptly once released is essential. If possible, replacing torch.load with safer deserialization methods or restricting deserialization to trusted sources is recommended in future versions.
Description
GPT-SoVITS-WebUI is a voice conversion and text-to-speech webUI. In versions 20250228v3 and prior, there is an unsafe deserialization vulnerability in bsroformer.py. The model_choose variable takes user input (e.g.a path to a model) and passes it to the uvr function. In uvr, a new instance of Roformer_Loader class is created with the model_path attribute containing the aformentioned user input (here called locally model_name). Note that in this step the .ckpt extension is added to the path. In the Roformer_Loader class, the user input, here called model_path, is used to load the model on that path with torch.load, which can lead to unsafe deserialization. At time of publication, no known patched versions are available.
