Technical details
The vulnerability stems from unconditional proxy trust (trustProxies at '*') in the application middleware combined with improper validation of the X-Forwarded-Host header in admin layout pages. An unauthenticated attacker can inject an arbitrary host value via the X-Forwarded-Host header, causing the server to load JavaScript assets from an attacker-controlled origin. When responses are cached by shared proxies, subsequent administrators are served the malicious cached content and execute attacker-supplied JavaScript in their authenticated browser contexts.
