## Technical details

The vulnerability is a stored/reflected cross-site scripting (XSS) flaw in QloApps' back-office list helper template (list_header.tpl). The application renders POST parameters from list filter requests directly into HTML input value attributes without proper escaping or sanitization. An attacker can craft a malicious POST request with JavaScript payloads in filter parameters and trick an authenticated admin into submitting it (via CSRF or social engineering), causing the JavaScript to execute in the admin's browser session. This allows the attacker to read administrative data, create/modify records, or perform other privileged actions. The vulnerability affects versions through 1.7.0 and requires the victim to be authenticated and to submit the malicious form.
