The All-in-One WP Migration WordPress plugin before 7.63 uses the wrong content type, and does not properly escape the response from the ai1wm_export AJAX action, allowing an attacker to craft a request that when submitted by any visitor will inject arbitrary html or javascript into the response that will be executed in the victims session. Note: This requires knowledge of a static secret key

The All-in-One WP Migration plugin for WordPress is vulnerable to arbitrary file deletion via directory traversal due to insufficient file validation via the ~/lib/model/class-ai1wm-backups.php file, in versions up to, and including, 7.58. This can be exploited by administrative users, and users who have access to the site's secret key.
