 - FastMCP is the standard framework for building MCP applications. Prior to version 2.14.2, the server does
 not properly respect the resource parameter submitted by the client in the authorization and token

 passed to the OAuthProxy during initialization. This issue has been patched 2.14.2. (CVE-2025-69196)

Solution

Update the fastmcp library and its related packages to version 2.14.2 or later.
