A path traversal vulnerability allowing arbitrary file write has been identified in Dayoooun hwpx-mcp version 0.2.0. This issue arises in the MCP Interface component, specifically within the 'save_document', 'export_to_text', and 'export_to_html' functions. The vulnerability allows remote exploitation by manipulating the 'output_path' argument, enabling writes to arbitrary locations on the server's filesystem. The issue has been publicly disclosed, and the project maintainers have not yet responded to reports about this vulnerability.
It is recommended to update the MCP server to a version that addresses this vulnerability. Until a patch is available, restrict access to the MCP server to trusted users and clients, and run the server under a low-privilege account with limited writable directories.
