CVE-2022-1895Public exploitNetwork attack vector

Construction mode deactivation via nonce-free admin request

Published Jun 20, 2022 · Updated Aug 3, 2024

CSRF in the underConstruction WordPress plugin before 1.20 allows remote attackers to disable construction mode through an administrator. The dashboard handler accepts the turnOffUnderConstructionMode query parameter on wp-admin/index.php and changes the mode without verifying a CSRF nonce. An administrator must remain logged in and load attacker-controlled HTML; the resulting request makes the site publicly accessible.
