**Name of the Vulnerable Software and Affected Versions** Vocos (affected versions not specified) **Description** The software instantiates classes based on a configuration file without restricting which classes can be named. The `instantiate class` function in `vocos/pretrained.py` uses the `class path` value from the configuration to import a module via ` import ` and resolve an attribute using `getattr`, subsequently calling the result as `args class(*args, **kwargs)` with arguments from the `init args` mapping. Because there is no allowlist to constrain the dotted path, a configuration file can specify any importable callable and its arguments. This issue is reachable through `Vocos.from hparams` for `feature extractor`, `backbone`, and `head` entries, as well as through `Vocos.from pretrained`, which downloads a `config.yaml` from a specified Hugging Face repository. Consequently, loading a model from an untrusted repository allows the repository owner to execute arbitrary code during the loading process. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
