The All-In-One Security (AIOS) – Security and Firewall plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'tab' parameter in all versions up to, and including, 5.2.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The UpdraftPlus: WordPress Backup & Migration Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.23.10. This is due to a lack of nonce validation and insufficient validation of the instance_id on the 'updraftmethod-googledrive-auth' action used to update Google Drive remote storage location. This makes it possible for unauthenticated attackers to modify the Google Drive location that backups are sent to via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This can make it possible for attackers to receive backups for a site which may contain sensitive information.
