The 404 Solution plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URLs in all versions up to, and including, 2.35.19 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 404 Solution plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.35.17 via the export feature. This makes it possible for unauthenticated attackers to extract sensitive data such as redirects including GET parameters which may reveal sensitive information.

The 404 Solution WordPress plugin before 2.35.8 does not properly sanitise and escape a parameter before using it in a SQL statement, leading to a SQL injection exploitable by high privilege users such as admins.
