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."}],"title":"User Registration & Membership <= 5.2.8 - Cross-Site Request Forgery to trigger_bulk_action()","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/713c4652-9ca0-41f7-9a93-8186d9b359e8?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L687"},{"url":"https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L667"},{"url":"https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L140"},{"url":"https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L36"},{"url":"https://plugins.trac.wordpress.org/changeset/3741339/user-registration/trunk/includes/admin/class-ur-admin-user-list-manager.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-352 Cross-Site Request Forgery (CSRF)","cweId":"CWE-352","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","baseScore":4.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Jonah Burgess (CryptoCat)"}],"timeline":[{"time":"2026-09-17T13:57:17.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-16T14:40:54.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-92978","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-10-18T11:08:17.533448Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-18T11:22:46.625Z"}}]}}
