Technical details
The vulnerability is a reflected or stored cross-site scripting (CWE-79) flaw in the ui_notification node component of node-red-dashboard versions prior to 2.17.0. The node accepts and renders raw HTML by default without proper sanitization, allowing attackers with dashboard access to inject arbitrary JavaScript code. The attack requires user interaction (a user must view the dashboard) and low privileges (basic user access to Node-RED). An attacker can execute arbitrary JavaScript in the victim's browser context, potentially stealing sensitive data or session tokens. The fix was released in version 2.17.0.
