This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Grav admin plugin prior to version 1.11.0-beta.1. Attackers can inject malicious scripts into the data[header][template] parameter via the /admin/pages/[page] endpoint. The injected script is stored in the page's frontmatter and executed automatically when the affected content is rendered in the admin interface or frontend view.
How can this vulnerability impact me? :
The vulnerability allows attackers to execute malicious scripts within the administrative interface or frontend of the Grav application. This can lead to unauthorized actions, data theft, session hijacking, or other malicious activities performed with the privileges of the affected user.
What immediate steps should I take to mitigate this vulnerability?
Upgrade the Grav admin plugin to version 1.11.0-beta.1 or later, as this version contains the fix for the Stored Cross-Site Scripting (XSS) vulnerability in the /admin/pages/[page] endpoint. Avoid using vulnerable versions prior to 1.11.0-beta.1 to prevent exploitation.
