Unauthenticated SQL injection via email.php id parameter
Published May 30, 2026 · Updated May 30, 2026
SQL injection in MGB OpenSource Guestbook 0.7.0.2 allows remote attackers to read database data through a crafted email.php request. The email.php endpoint incorporates the untrusted id GET parameter into an SQL query without neutralizing SQL syntax, enabling UNION-based query manipulation. No authentication or user interaction is required; network access to the endpoint is enough to enumerate table and column names and retrieve database information.
