  "details": "### Summary\nDue to insufficient validation on the content of new FAQ posts, it is possible for authenticated users to inject malicious HTML or JavaScript code that can impact other users viewing the FAQ. This vulnerability arises when user-provided inputs in FAQ entries are not sanitized or escaped before being rendered on the page.\n\n### Details\nAn attacker can inject malicious HTML content into the FAQ editor at http://localhost/admin/index.php?action=editentry, resulting in a complete disruption of the FAQ page\u0027s user interface. By injecting malformed HTML elements styled to cover the entire screen, an attacker can render the page unusable. This injection manipulates the page structure by introducing overlapping buttons, images, and iframes, breaking the intended layout and functionality. \n\n### PoC\n\n1. In the source code of a FAQ Q\u0026A post, insert the likes of this snippet:\n```\n\u003cp\u003e\u0026lt;--`\u003cimg src=\"\u0026#96;\"\u003e --!\u0026gt;\u003c/p\u003e\n\u003cdiv style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%;\"\u003e\u003cform\u003e\u003cbutton\u003eHTML INJECTION 1\u003cimg\u003e \u003cimg\u003e \u003cimg\u003e \u003cimg\u003e \u003ciframe\u003e\u003c/iframe\u003e\u003c/button\u003e\n\u003cdiv style=\"xg-p: absolute; top: 0; left: 0; width: 100%; height: 100%;\"\u003ex\u003c/div\u003e\n\u003cbutton\u003eHTML INJECTION 2\u003ciframe\u003e\u003c/iframe\u003e \u003ciframe\u003e\u003c/iframe\u003e \u003c/button\u003e\u003c/form\u003e\u003c/div\u003e\n```\n\n![image](https://github.com/user-attachments/assets/7c12ff40-1978-4dee-b501-c48f3ea2b9ba)\n2.
