The All-in-One WP Migration and Backup plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Import in all versions up to, and including, 7.97 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

The All-in-One WP Migration and Backup plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 7.86 through publicly exposed log files. This makes it possible for unauthenticated attackers to view potentially sensitive information such as full paths contained in the exposed log files.
