What is CVE-2025-27780?
CVE-2025-27780 is a high-severity unsafe deserialization vulnerability in IAHispano Applio, published on 19 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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: CWE-502
