Recommendation: Plan a near-term fix — a public PoC already exists.
Guardian language-system fails to sanitize the id GET parameter before inserting it into HTML source and form action attributes in media.php (lines 119, 129). An authenticated attacker can craft a URL that injects script tags executing in the victim's browser session.
