This makes it possible for unauthenticated attackers to force administrators to approve pending user registrations or deny arbitrary user accounts, locking targeted users out of the site via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. An attacker can bypass the earlier nonce check in trigger_query_actions() by supplying an empty new_role parameter, which causes that handler to return early and cede control to the unprotected trigger_bulk_action() handler; the exit() call at the end of that handler additionally prevents WordPress core's own bulk-users nonce validation from executing.","state":0,"publishedAt":"2026-10-17T03:43:29.067+00:00","modifiedAt":"2026-10-18T11:22:46.625+00:00","affected":[{"ecosystem":"Vendor product","name":"User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wpeverest\",\n                    \"product\": \"User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"5.2.8\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","score":4.3,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/713c4652-9ca0-41f7-9a93-8186d9b359e8?source=cve","https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L687","https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L667","https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L140","https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L36","https://plugins.trac.wordpress.org/changeset/3741339/user-registration/trunk/includes/admin/class-ur-admin-user-list-manager.php"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92978","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92978","identifiers":["CVE-2026-92978"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
