{"schema":"threatline.record/2","record":{"id":"CVE-2026-92978","aliases":[],"summary":"User Registration & Membership <= 5.2.8 - Cross-Site Request Forgery to trigger_bulk_action()","details":"The User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.2.8 This is due to missing or incorrect nonce validation on the trigger_bulk_action function. 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.","categories":["Unclassified"],"product":"User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder","vendor":"wpeverest","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92978","source_modified_at":"2026-10-18T11:22:46.625Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder","vendor":"wpeverest","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.2.8","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":4.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00154,"percentile":0.04174,"score_date":"2026-10-23"},"published_at":"2026-10-17T03:43:29.067Z","modified_at":"2026-10-18T11:22:46.625Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92978","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-18T11:22:46.625Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92978","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/713c4652-9ca0-41f7-9a93-8186d9b359e8?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L687"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L667"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L140"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/user-registration/tags/5.2.8/includes/admin/class-ur-admin-user-list-manager.php#L36"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3741339/user-registration/trunk/includes/admin/class-ur-admin-user-list-manager.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-18T11:08:17.533448Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-18T11:22:46.625Z","content_hash":"a8de5dec76ec550465dc806b7344ced840bc5829529a30e9e231fe7a59e9424d"}}
