Summary
The All-in-One WP Migration and Backup plugin for WordPress is vulnerable to SQL Injection via archive restore functionality in all versions up to, and including, 7.109 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This can be leveraged to obtain the ai1wm_secret_key when a site administrator performs an archive restore and achieve remote code execution once able to leverage the ai1wm_secret_key value.
