CVE-2026-79784: Vocos class instantiation from configuration via from_pretrained

Source: NVD(opens in a new tab)
Identifier: CVE-2026-79784
Published: August 25, 2026
Record updated: October 9, 2026

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.
EPSS: 0.6%

Summary

Vocos, through its instantiate_class function in vocos/pretrained.py, imports and calls whatever class_path a configuration file names, with arguments from its init_args, and applies no allowlist. Vocos.from_pretrained passes a config.yaml downloaded from a caller-named Hugging Face repository straight to from_hparams. Loading a model from a repository the user does not control therefore runs code chosen by that repository's owner.

Mitigation
