Vulnerability details
The vulnerability allows a remote authenticated user to escalate privileges within the application.
NodeBB before version 1.14.3 has a bug introduced in version 1.12.2 in the validation logic that makes 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.
