Technical details
The backup addon's export functionality has a missing authorization check: while sensitive tables (rex_user, rex_user_session, rex_user_passkey) were omitted from default selection, they remained accessible and exportable by any non-admin user with the backup[export] permission. An attacker with this permission can export rex_user_session to obtain plaintext session IDs and stay-logged-in keys for account takeover, or rex_user to retrieve password hashes for offline cracking. The vulnerability requires the precondition that an admin has explicitly granted backup[export] to a non-admin user, and affects REDAXO versions before 5.21.5.
