CVE-2023-46821Network attack vector

Database disclosure via unsanitized CSP log filters

Published Nov 6, 2023 · Updated Apr 28, 2026

SQL injection in Milan Petrovic GD Security Headers 1.7 and earlier allows remote authenticated users to read database data via CSP log filters. The CSP logs panel passes the filter-vd and filter-ed parameters into existing database queries without sufficient escaping or prepared-query handling. Administrator-level WordPress access is required; a union-based payload can append query content and extract sensitive database information.
