No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The All-in-One WP Migration and Backup WordPress plugin before 7.111 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 All-in-One WP Migration and Backup WordPress plugin before 7.111's own import capability, which is not a default configuration.
