What it is

Guardian language-system fails to sanitize the id GET parameter before inserting it into multiple HTML form action attributes in text_file.php (lines 94, 101, 323, 403, 826, 852). An authenticated attacker can craft a URL that injects script tags executing in the victim's browser session.
