The All-in-One WP Migration Unlimited Extension plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 2.83. This is due to the 'Ai1wmve_Schedules_Controller::save' handler for 'admin_post_ai1wm_schedule_event_save' not verifying user capabilities before saving schedule data. This makes it possible for authenticated attackers, with subscriber-level access and above, to create scheduled export jobs and send backup notifications to attacker-controlled email addresses. Because such notifications include the random backup filename, full site backups can subsequently be downloaded from the target site, resulting in sensitive information exposure.
