| Описание | This vulnerability allows you to take advantage of the browserLang parameter to inject malicious code and use the fact that there is no CSRF token for the login request, allowing you to concatenate the CSRF vulnerability with XSS. To reproduce, simply save the HTML code provided below in a .html file and open it in your browser, which will show the alert prompt as proof of concept.
