CVE-2026-58116Public exploitNetwork attack vector

Remote code execution via trusted model loading

Published Jun 30, 2026 · Updated Jun 30, 2026

Code injection in hiyouga LlamaFactory 0.9.5 and earlier allows remote attackers with WebUI access to execute Python code via a model path. The Chat and Training loaders pass the submitted path to Hugging Face AutoTokenizer.from_pretrained() and AutoModel.from_pretrained() while forcing trust_remote_code=True, so repository Python modules execute without validating the source. Reachability requires access to the WebUI; successful code runs with the server process's privileges and can read, alter, or interrupt resources available to that process.
