CVE-2023-47769Network attack vector

Unauthenticated maintenance-mode bypass via spoofed IP data

Published Jun 4, 2024 · Updated Apr 28, 2026

IP restriction bypass in WP Maintenance 6.1.3 and earlier allows remote attackers to view pages hidden by maintenance mode. The IP access-control path accepts spoofable client-address data when deciding whether a request matches the configured access list; public records do not identify the exact request field. Exploitation is unauthenticated and requires IP-based access controls to protect content, with no reported write or service-interruption impact.
