Multiple Stored Cross Site Scripting (XSS) vulnerabilities exist in the YOURLS Admin Panel, Versions 1.5 - 1.7.10. An authenticated user must modify a PHP plugin with a malicious payload and upload it, resulting in multiple stored XSS issues.
Cross-site scripting (XSS) vulnerability in the administrator panel in Yourls 1.7 allows remote attackers to inject arbitrary web script or HTML via a URL that is processed by the Shorten functionality.
Your Own URL Shortener (YOURLS) 1.5 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by includes/auth.php and certain other files.
