The vulnerability exists because the activation handler passes the attacker-supplied role value directly to `WP_User::set_role()` with no allow-list validation, and the 4.0.3 reserved-name check exempts pre-existing form fields from the block, allowing a legacy field with meta-name `role` to persist and bridge attacker-controlled request input into the serialized signup record stored in `wp_signups`. This makes it possible for unauthenticated attackers to gain a fully activated WordPress administrator account by submitting `role=administrator` through the public `[wppb-register]` shortcode form and subsequently clicking the confirmation activation link. Exploitation requires the site to have a legacy form field with meta-name `role` carried over from before the 4.0.3 upgrade, email confirmation enabled, and open user registration \u2014 all stable site-state conditions once established.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The User Profile Builder \u2013 Beautiful User Registration Forms, User Profiles &amp; User Role Editor plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.0.3 vi<\/p>\n","protected":false},"template":"","meta":[],"categories":[],"tags":[],"class_list":["post-40328","vuln","type-vuln","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.54iter.cn\/index.php?rest_route=\/wp\/v2\/vuln\/40328","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.54iter.cn\/index.php?rest_route=\/wp\/v2\/vuln"}],"about":[{"href":"https:\/\/www.54iter.cn\/index.php?rest_route=\/wp\/v2\/types\/vuln"}],"wp:attachment":[{"href":"https:\/\/www.54iter.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=40328"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.54iter.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=40328"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.54iter.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=40328"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
