This makes it possible for unauthenticated attackers to view privacy-restricted member profile field values — including fields explicitly configured as owner-only, members-only, or role-restricted — by querying the publicly accessible wp_ajax_nopriv_um_get_members endpoint. The nonce required by the endpoint ('um-frontend-nonce') is emitted to all unauthenticated visitors via wp_localize_script, meaning it provides no meaningful access control and any anonymous visitor can satisfy the endpoint's authentication requirements."}],"title":"Ultimate Member <= 2.13.1 - Missing Authorization to Unauthenticated Sensitive Profile Field Disclosure via Member Directory Field Privacy Bypass","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/cde81421-e080-4530-87a5-6515f1c9800b?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-member-directory.php#L2795"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-member-directory.php#L2839"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-fields.php#L144"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/um-actions-profile.php#L1319"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-ajax-common.php#L61"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/um-short-functions.php#L1579"},{"url":"https://github.com/ultimatemember/ultimatemember/releases/tag/2.14.0"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Mutantgun"}],"timeline":[{"time":"2026-09-17T21:17:49.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-02T13:59:43.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-93428","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-10-03T15:36:33.111395Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-03T15:42:46.923Z"}}]}}
