CVE-2026-28562Network attack vector

Unauthenticated credential disclosure via ORDER BY injection

Published Feb 28, 2026 · Updated Feb 28, 2026

SQL injection in gVectors Team wpForo Forum before 2.4.15 allows remote attackers to extract WordPress database credentials. Topics::get_topics() places the attacker-controlled wpfob value into an ORDER BY clause after esc_sql(), which does not neutralize unquoted SQL expressions. No authentication or user interaction is required; crafted CASE WHEN expressions provide a blind boolean oracle for credential extraction.
