CVE-2026-5753All-in-One WP Migration Unlimited Extension <= 2.83 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Backup Schedule Creation and Backup File Download
Medium 6.5
In plain English
A medium-severity missing authorization in All-in-One WP Migration Unlimited Extension from servmask. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 19% of all known vulnerabilities).
Official 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.
