Unauthenticated admin access via unterminated redirect
Published Jun 1, 2026 · Updated Jun 1, 2026
Authentication bypass in a4m4 Student Management System allows remote attackers to access admin pages without a valid session. Admin PHP files redirect unauthenticated requests but omit exit or die, so PHP continues rendering protected content after the redirect. The CNA rates exploitation as requiring user interaction, while the published proof of concept shows that a client ignoring the 302 response can read admin forms and reach student-record operations.
