All-in-One WP Migration and Backup < 7.111 - Authenticated Privilege Escalation to Admin via Import Secret Key Disclosure

Description

The plugin does not perform any capability check on several of its AJAX actions, gating them only on an installation-wide secret which it discloses to any user permitted to export the site, allowing such a user to import an arbitrary site archive and gain administrator access. Exploitation requires an administrator to have granted the export capability to a role that does not hold the plugin's own import capability, which is not a default configuration.
