Limny is a free and open-source content management framework with a focus on ease to use and develop. It can be used as a stable and powerful core for heavy and light web applications by having main features of web applications such as user management, multilingual system and multiple theme support. Also its rich graphic library helps designers to create colorable themes instead of designing multiple themes.
Limny suffers from a XSS issue in '/admin/login.php' that uses the 'PHP_SELF' variable. The vulnerability is present because there isn't any filtering to the mentioned variable in the affected script. Attackers can exploit this weakness to execute arbitrary HTML and script code in a user's browser session.
