Scanner	multi_agent_ai
Rule	V-005
File	examples/express-session-example/esm/index.js:23

Description: The POST /incr endpoint modifies session state without any authentication or authorization checks. The endpoint does not verify that a valid authenticated user is making the request, allowing unauthenticated users to increment the counter. While this is a simple example, it demonstrates a critical pattern of missing authorization on state-changing operations.
