Hi Maintainer, I’ve reviewed the P1 backend security issue and can implement Socket.IO authentication, room-join authorization, payload validation, and strict private-room isolation. I’ll ensure users cannot subscribe to another user’s updates and add focused tests for authorized and unauthorized access. Kindly assign this to me.
