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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-352"],"references":["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/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#L687","https://plugins.trac.wordpress.org/changeset/3741339/user-registration/trunk/includes/admin/class-ur-admin-user-list-manager.php"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-92978","score":0.00154,"percentile":0.04463,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
