CVE-2023-38519Network attack vector

Database disclosure via unvalidated tag filters

Published Dec 20, 2023 · Updated Apr 28, 2026

SQL injection in MainWP Dashboard 4.4.3.3 and earlier allows remote authenticated users to read database data via crafted tag filters. The Manage Clients path passes unvalidated by_tags values into an implode-built SQL IN clause in get_wp_client_by instead of constraining them to numeric IDs. Administrator access to the Dashboard is required, and successful injection exposes data readable by the WordPress database account.
