CVE-2021-3332Public exploitNetwork attack vector

Login-page disclosure via unchecked post_password branch

Published Mar 1, 2021 · Updated Aug 3, 2024

Authentication bypass in WPS Hide Login 1.6.1 allows remote attackers to expose the standard WordPress login page via a crafted POST. In classes/plugin.php, wp_loaded() checks only for the absence of post_password and has no alternate branch, so supplying the field skips request interception. No authentication is required; the bypass reveals the otherwise hidden login endpoint but does not itself grant account access.
