{"id":"CVE-2026-79784","state":"PUBLISHED","title":"Vocos through 0.1.0 Arbitrary Code Execution via Unrestricted class_path in Model Configuration","description":"Vocos instantiates a class named by a configuration file without restricting which class may be named. instantiate_class in vocos/pretrained.py takes the class_path value from the configuration, splits it into a module and an attribute, imports the module with __import__, resolves the attribute with getattr, and calls the result as args_class(*args, **kwargs) where kwargs is the config's own init_args mapping. No allowlist constrains the dotted path, so a configuration may name any importable callable and supply the arguments it is called with. Vocos.from_hparams reaches this for each of the feature_extractor, backbone and head entries, and Vocos.from_pretrained reaches it with a remote file: it downloads config.yaml from a caller-named Hugging Face repository and passes it straight to from_hparams. Loading a model from a repository the user does not control therefore executes code of the repository owner's choosing in the loading process. The neighbouring torch.load of the downloaded weights is a separate matter and is constrained on PyTorch releases that default weights_only to true, which leaves this path as the reachable one.","publishedAt":"2026-08-25T15:16:12.456Z","updatedAt":"2026-09-24T14:19:42.300Z","severity":{"score":8.6,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["gemelo-ai vocos"],"affected":[{"vendor":"gemelo-ai","product":"vocos","packageURL":"pkg:pypi/vocos","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"0.1.0","versionType":"semver"}],"repo":"https://github.com/gemelo-ai/vocos"}],"references":["https://github.com/gemelo-ai/vocos","https://github.com/gemelo-ai/vocos/issues/76","https://github.com/gemelo-ai/vocos/blob/main/vocos/pretrained.py","https://pypi.org/project/vocos/","https://www.vulncheck.com/advisories/vocos-through-arbitrary-code-execution-via-unrestricted-class-path-in-model-configuration"],"weaknesses":["CWE-470"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/79xxx/CVE-2026-79784.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-79784","state":"PUBLISHED","datePublished":"2026-08-25T15:16:12.456Z","dateUpdated":"2026-09-24T14:19:42.300Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-08-25T14:32:37.762Z"},"containers":{"cna":{"title":"Vocos through 0.1.0 Arbitrary Code Execution via Unrestricted class_path in Model Configuration","descriptions":[{"lang":"en","value":"Vocos instantiates a class named by a configuration file without restricting which class may be named. instantiate_class in vocos/pretrained.py takes the class_path value from the configuration, splits it into a module and an attribute, imports the module with __import__, resolves the attribute with getattr, and calls the result as args_class(*args, **kwargs) where kwargs is the config's own init_args mapping.
