The project already applies this step-up middleware to sensitive operations such as: - Nginx config create/edit/rename/delete; - site save/delete/enable/disable/rename/duplicate; - stream save/delete/enable/disable/rename/duplicate; - settings save and protected secret reads; - backup restore. However, several similarly sensitive authenticated mutation routes remain outside `RequireSecureSession()`. An attacker who obtains an authenticated JWT/session for a 2FA-enabled user, but does not have the victim's fresh OTP/passkey secure-session token, can still perform those operations. The affected route groups include: - automatic backup create/modify/delete/restore/test-S3 operations; - DNS credential create/edit/delete operations; - certificate and ACM",
