- CVE-2025-14477, 13 Dec 2025
- The 404 Solution plugin for WordPress is vulnerable to SQL Injection in all versions up to, and including, 3.1.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This is due to improper sanitization of the `filterText` parameter in the `ajaxUpdatePaginationLinks` AJAX action. The sanitization logic can be bypassed by using the sequence `*$/` which becomes `*/` after the `$` character is removed, allowing attackers to escape SQL comment contexts. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database via a time-based blind SQL injection technique.

- CVE-2024-11277, 20 Nov 2024
- 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. CVE record
- CVE-2024-11094, 16 Nov 2024
- 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 data such as redirects including GET parameters which may reveal sensitive information. On most sites this is unlikely to be the case. CVE record
- CVE-2024-1068, 11 Mar 2024
- 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. CVE record
What to do if you run 404 Solution
If you run 404 Solution, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
