The vulnerability resides in the \u003ccode\u003eget_pdf_path\u003c/code\u003e function within the \u003ccode\u003esrc/spire_pdf_mcp/server.py\u003c/code\u003e file. By manipulating the \u003ccode\u003efilepath\u003c/code\u003e argument, a remote attacker can bypass directory traversal restrictions and potentially access sensitive files on the server. Public exploits are available, increasing the risk of exploitation. The vendor has been notified but has not yet provided a patch or response.
