CVE-2020-15149

Account takeover in NodeBB

Description

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. This could lead to a privilege escalation event due via an account takeover. As a workaround you may cherry-pick the following commit from the project's repository to your running instance of NodeBB: 16cee1b03ba3eee177834a1fdac4aa8a12b39d2a. This is fixed in version 1.14.3.
