Technical details
The vulnerability is a path traversal flaw in the Triton MLflow plugin that fails to properly sanitize model names provided by users. An attacker can supply a crafted path (e.g., containing "../" sequences) as a model name to access files outside the configured model repository directory. No authentication is required—the plugin accepts user-controlled input directly. Successful exploitation allows reading arbitrary files (information disclosure), writing or modifying files outside the repository, and potentially causing denial of service. A patch is expected from NVIDIA.
