Open ISES Tickets before 3.44.2 contains hardcoded MySQL database credentials in loader.php (a public-facing database utility) that are committed to the source repository. Any actor with access to the public source tree (or an unauthenticated attacker with read access to the file on a deployed installation) can read the username, password, and database name and use them to connect to the database if it is reachable from their network.
