{"id":"CVE-2025-14533","state":"PUBLISHED","title":"Advanced Custom Fields: Extended <= 0.9.2.1 - Unauthenticated Privilege Escalation via Insert User Form Action","description":"The Advanced Custom Fields: Extended plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 0.9.2.1. This is due to the 'insert_user' function not restricting the roles with which a user can register. This makes it possible for unauthenticated attackers to supply the 'administrator' role during registration and gain administrator access to the site. Note: The vulnerability can only be exploited if 'role' is mapped to the custom field.","publishedAt":"2026-01-20T09:25:00.542Z","updatedAt":"2026-04-08T17:25:47.419Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["hwk-fr Advanced Custom Fields: Extended"],"affected":[{"vendor":"hwk-fr","product":"Advanced Custom Fields: Extended","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"0.9.2.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/d44f8af2-3525-4b00-afa8-a908250cc838?source=cve","https://plugins.trac.wordpress.org/browser/acf-extended/tags/0.9.2.1/includes/modules/form/module-form-action-user.php#L636","https://plugins.trac.wordpress.org/browser/acf-extended/tags/0.9.2.2/includes/fields/field-user-roles.php#L437","https://plugins.trac.wordpress.org/browser/acf-extended/tags/0.9.2.2/includes/modules/form/module-form-action-user.php#L356"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/14xxx/CVE-2025-14533.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-14533","state":"PUBLISHED","datePublished":"2026-01-20T09:25:00.542Z","dateUpdated":"2026-04-08T17:25:47.419Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-12-11T10:11:32.336Z"},"containers":{"cna":{"title":"Advanced Custom Fields: Extended <= 0.9.2.1 - Unauthenticated Privilege Escalation via Insert User Form Action","descriptions":[{"lang":"en","value":"The Advanced Custom Fields: Extended plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 0.9.2.1.
