Summary

Dify, an open-source LLM app development platform, is affected before 1.16.0. The PUT /console/api/apps/<app_id>/server endpoint fetches an MCP server by a client-supplied ID without checking that it belongs to the requested app and tenant (CWE-639). An authenticated workspace member can change another application's MCP server status and parameters, potentially redirecting data or disabling the service.

Description from the CNA

Dify is an open-source LLM app development platform. Prior to 1.16.0, the PUT /console/api/apps/<app_id>/server endpoint in api/controllers/console/app/mcp_server.py used AppMCPServerController.put() to retrieve an AppMCPServer by the client-supplied server ID without verifying that the server belonged to the requested application and tenant. An authenticated workspace member could therefore change another application's MCP server status and parameters, potentially redirecting data or disabling the service. This issue is fixed in version 1.16.0.
