source: https://www.securityfocus.com/bid/25923/info GForge is prone to a cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied data. A fix is available from the vendor. Exploiting this issue could allow an attacker to steal cookie-based authentication credentials and to launch other attacks. This issue affects GForge 4.6; other versions may also be affected. http://www.example.com/GForgePath/account/verify.php?confirm_hash="/>
