Nodebb is an open source Node.js based forum software. In affected versions incorrect logic present in the token verification step unintentionally allowed master token access to the API. The vulnerability has been patch as of v1.18.5. Users are advised to upgrade as soon as possible.

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.

Controllers.outgoing in controllers/index.js in NodeBB before 0.7.3 has outgoing XSS.

Multiple cross-site scripting (XSS) vulnerabilities in NodeBB before 0.7 allow remote attackers to inject arbitrary web script or HTML via vectors related to (1) javascript: or (2) data: URLs.
