Jonathan de Jong vulnerabilities and threats

CVE-2026-78288 is a critical unauthenticated SQL Injection vulnerability affecting Beautiful Taxonomy Filters versions up to 2.4.6. This flaw allows remote attackers to execute SQL commands without authentication, potentially leading to high confidentiality impact and limited availability impact. No official patch or remediation guidance is currently confirmed from the vendor.

The Beautiful taxonomy filters plugin for WordPress is vulnerable to SQL Injection via the 'selects[0][term]' parameter in all versions up to, and including, 2.4.3 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.
