|---|
| Description | An arbitrary file write vulnerability (CWE-73) has been identified in hwpx-mcp-server version 0.2.0 (commit 87850fd), specifically within the save_document, export_to_text, and export_to_html MCP tools. The server accepts caller‑controlled output_path arguments and writes to those paths without validating that the destination resides inside a safe workspace, allowing parent‑directory traversal or absolute paths. An attacker with network access to the MCP interface can create or overwrite files at arbitrary locations writable by the server process, leading to integrity loss, configuration corruption, or denial of service. No fixed version is available at the time of reporting. |
