Applio is a voice conversion tool. Versions 3.2.8-bugfix and prior are vulnerable to unsafe deserialization in model_information.py. model_name in model_information.py takes user-supplied input (e.g. a path to a model) and pass that value to the run_model_information_script and later to model_information function, which loads that model with torch.load in rvc/train/process/model_information.py (on line 16 in 3.2.8-bugfix), which is vulnerable to unsafe deserialization. The issue can lead to remote code execution. A patch is available in the main branch of the repository.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Applio Applio * 3.2.8-bugfix (including)

Potential Mitigations

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
