{"id":"CVE-2026-1492","state":"PUBLISHED","title":"User Registration & Membership <= 5.1.2 - Unauthenticated Privilege Escalation via Membership Registration","description":"The User Registration & Membership – Custom Registration Form Builder, Custom Login Form, User Profile, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to improper privilege management in all versions up to, and including, 5.1.2. This is due to the plugin accepting a user-supplied role during membership registration without properly enforcing a server-side allowlist. This makes it possible for unauthenticated attackers to create administrator accounts by supplying a role value during membership registration.","publishedAt":"2026-03-03T04:33:20.922Z","updatedAt":"2026-04-08T17:03:11.800Z","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":["wpeverest User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder"],"affected":[{"vendor":"wpeverest","product":"User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.1.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/7e9fec92-f471-4ce9-9138-1c58ad658da2?source=cve","https://plugins.trac.wordpress.org/changeset/3469042/user-registration"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1492.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1492","state":"PUBLISHED","datePublished":"2026-03-03T04:33:20.922Z","dateUpdated":"2026-04-08T17:03:11.800Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-27T14:38:16.707Z"},"containers":{"cna":{"title":"User Registration & Membership <= 5.1.2 - Unauthenticated Privilege Escalation via Membership Registration","descriptions":[{"lang":"en","value":"The User Registration & Membership – Custom Registration Form Builder, Custom Login Form, User Profile, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to improper privilege management in all versions up to, and including, 5.1.2.
