CVE-2026-5753 (GCVE-0-2026-5753)

Vulnerability from cvelistv5 – Published: 2026-05-06 03:27 – Updated: 2026-05-06 12:57

Title

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

Summary

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.

Severity

6.5 (Medium)
