CVE-2026-18958Public exploitNetwork attack vector

Authentication bypass via concatenated login query

Published Aug 5, 2026 · Updated Aug 5, 2026

SQL injection in the Login component of imranrisal-dev Student Management System allows remote attackers to bypass authentication. UserModel.php's validateUser() concatenates request-supplied username and password values into a SELECT query and executes it with mysqli_query(). No credentials or user interaction are required; any returned row creates an authenticated session and grants access as that student or staff account.
