Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Reflected XSS: The session_example.php script directly outputted the unsanitized $_SERVER['PHP_SELF'] variable, allowing attackers to inject malicious HTML or JavaScript into the user's browser session. Developers should avoid raw echo statements on global server variables without output encoding.
