CVE-2026-105761: Langgenius Dify

High severity, CVSS 7.1. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Langgenius Dify: before 1.16.0 (fixed in 1.16.0)
