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.","state":0,"publishedAt":"2026-10-03T02:25:36.239+00:00","modifiedAt":"2026-10-03T15:42:46.923+00:00","affected":[{"ecosystem":"Vendor product","name":"Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ultimatemember\",\n                    \"product\": \"Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"2.13.1\",\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:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/cde81421-e080-4530-87a5-6515f1c9800b?source=cve","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-member-directory.php#L2795","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-member-directory.php#L2839","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-fields.php#L144","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/um-actions-profile.php#L1319","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-ajax-common.php#L61","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/um-short-functions.php#L1579","https://github.com/ultimatemember/ultimatemember/releases/tag/2.14.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93428","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93428","identifiers":["CVE-2026-93428"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
