CVE-2026-5753 Details
Description
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.
A missing authorization vulnerability has been identified in the All-in-One WP Migration Unlimited Extension for WordPress, affecting versions through 2.83. The issue arises because the 'Ai1wmve_Schedules_Controller::save' handler for 'admin_post_ai1wm_schedule_event_save' fails to verify user capabilities before saving schedule data. This vulnerability enables authenticated attackers with subscriber-level access and above to create scheduled export jobs and send backup notifications to email addresses controlled by the attacker. These notifications include the random backup filename, allowing full site backups to be downloaded from the target site, which could result in the exposure of sensitive information.
Users are advised to update the All-in-One WP Migration Unlimited Extension to version 2.84 or a newer patched version.
