CVE-2026-5753
All-in-One WP Migration Unlimited Extension <= 2.83 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Backup Schedule Creation and Backup File Download
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.

Action Type Old Value New Value Added Translation Title: All-in-One WP Migration Unlimited Extension de servmask, Description: El plugin All-in-One WP Migration Unlimited Extension para WordPress es vulnerable a Autorización Faltante en versiones hasta la 2.83, inclusive. Esto se debe a que el gestor 'Ai1wmve_Schedules_Controller::save' para 'admin_post_ai1wm_schedule_event_save' no verifica las capacidades del usuario antes de guardar los datos de la programación. Esto hace posible que atacantes autenticados, con acceso de nivel de suscriptor y superior, creen trabajos de exportación programados y envíen notificaciones de copia de seguridad a direcciones de correo electrónico controladas por el atacante. Debido a que dichas notificaciones incluyen el nombre de archivo de copia de seguridad aleatorio, las copias de seguridad completas del sitio pueden ser descargadas posteriormente del sitio objetivo, lo que resulta en la exposición de información sensible. -
