CVE-2022-1613Public exploitNetwork attack vector

Unauthenticated access bypass via spoofed IP headers

Published Sep 26, 2022 · Updated May 21, 2025

Authentication bypass in 10up Restricted Site Access before 7.3.2 allows remote attackers to access IP-restricted WordPress content. The get_client_ip_address method accepts client-controlled forwarding headers before PHP's REMOTE_ADDR and compares the resulting address against the configured IP allow list. Exploitation requires an enabled site restriction and an allow-listed address supplied in a trusted header; it exposes restricted front-end content without administrative access.
