What is CVE-2026-13331?

The Groundhogg plugin for WordPress is susceptible to SQL Injection through the 'search' parameter, affecting all versions prior to 4.5.5. This vulnerability arises from inadequate escaping of user-supplied input and the lack of sufficient preparation in the underlying SQL query structure. Authenticated attackers with marketer-level permissions or higher can exploit this weakness to inject malicious SQL queries, which may lead to unauthorized access to sensitive data stored in the database.
