Description
Versions of the package mcp-markdownify-server before 1.0.0 are vulnerable to Files or Directories Accessible to External Parties via the get-markdown-file tool. An attacker can craft a prompt that, once accessed by the MCP host, will allow it to read arbitrary files from the host running the server.
