Technical details
The model parameter form endpoint performs workspace-level authorization checking but the ModelSerializer.ModelParams class queries models by ID alone, omitting workspace_id filtering. An authenticated user with model read permission in any workspace can call /workspace/{attacker_workspace}/model/{victim_model_id}/model_params_form with a known victim model ID to read or PUT malicious parameters. This requires authentication and knowledge of a target model ID but allows cross-workspace integrity and confidentiality violations.
