|---|
| Description | The web-facing BioinfoMCP platform exposes POST /upload for converting uploaded manuals into generated MCP server artifacts. The route reads the uploaded file object from request.files, takes its client-supplied filename verbatim, and writes it using f.save(os.path.join("uploads", f.filename)).
Because the multipart filename field is attacker-controlled, an absolute path such as /tmp/bioinfomcp_poc.pdf overrides the intended uploads/ directory entirely, and traversal sequences can also escape it. The route then passes that attacker-chosen saved path into scripts/do_sth.py, so the unsafe path is not only written but also treated as the input artifact for the rest of the conversion workflow.
