Authentication bypass via forgeable school_auth cookie
Published May 31, 2026 · Updated May 31, 2026
Authentication bypass in School Student Management System allows remote attackers to impersonate any configured user through a forged cookie. The MY_Controller sign_auth_cookie method uses a published static encryption key to authenticate the role and user ID in school_auth, allowing valid HMAC-SHA256 values to be calculated offline. No account or user interaction is required; selecting the admin role and a valid identifier establishes an administrator session with access to protected data and functions.
