CVE-2024-3561Network attack vector

Authenticated database extraction via unprepared Term query

Published Jun 20, 2024 · Updated Apr 8, 2026

SQL injection in Custom Field Suite 2.6.7 and earlier allows remote authenticated users to extract database data via the Term field. The Term field renderer interpolates its stored value directly into a term ID IN clause and FIELD ordering expression without escaping or a prepared statement. Contributor-level WordPress access is required; injected SQL executes in existing database queries and permits sensitive information extraction.
