Technical details
The vulnerability is a stored cross-site scripting (XSS) flaw in Grav's Home Page editor that permits injection of JavaScript code. The attack requires administrative privileges to access the editor. The injected script is stored and executed in the browsers of visitors viewing the home page. The relevance as a true XSS vulnerability is disputed within the security community because administrators already have broad permissions to modify templates, install plugins, and upload executable content—meaning this does not expand the threat model significantly beyond existing admin capabilities. Patches or configuration restrictions may be available; refer to vendor documentation.
