OpenMed before 1.5.2 contains a remote code execution vulnerability in the PII privacy-filter model loading path. The privacy-filter dispatcher used broad substring matching on the user-supplied `model_name` parameter, allowing a value such as `attacker/foo-privacy-filter-bar` to route through a path that loads Hugging Face models with `trust_remote_code=True`. An unauthenticated attacker can supply a malicious model repository containing custom Transformers code via auto_map in `config.json` or `tokenizer_config.json`, which is imported and executed with the privileges of the OpenMed service process.
