{"id":"CVE-2026-19652","state":"PUBLISHED","title":"Divi Membership <= 2.2.0 - Unauthenticated Privilege Escalation via 'form_id' Parameter","description":"The Divi Membership plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 2.2.0. This is due to the `dmem_form_submit_handler()` function determining the new user's role by iterating all WordPress roles and calling `password_verify()` against an attacker-controlled bcrypt hash supplied in the `form_id` POST parameter, with no validation or whitelist of allowed roles. This makes it possible for unauthenticated attackers to register a new account with the administrator role by submitting a locally computed bcrypt hash of `administrator` as `form_id`, and when `auto_login=on` is submitted, be immediately authenticated as that administrator in the same request, resulting in full site takeover. Exploitation requires a WordPress nonce, but that nonce is publicly emitted on any page rendering the Divi Membership registration form and is therefore obtainable by any unauthenticated visitor.","publishedAt":"2026-10-02T13:29:05.573Z","updatedAt":"2026-10-03T15:42:47.812Z","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":["DiviEngine Divi Membership"],"affected":[{"vendor":"DiviEngine","product":"Divi Membership","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.2.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/81d46c7a-dfe4-4991-99cc-66e5c6d3e3c8?source=cve","https://diviengine.com/product/divi-membership/","https://diviengine.com/divi-membership-changelog/"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/19xxx/CVE-2026-19652.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-19652","state":"PUBLISHED","datePublished":"2026-10-02T13:29:05.573Z","dateUpdated":"2026-10-03T15:42:47.812Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-08-12T17:43:51.465Z"},"containers":{"cna":{"title":"Divi Membership <= 2.2.0 - Unauthenticated Privilege Escalation via 'form_id' Parameter","descriptions":[{"lang":"en","value":"The Divi Membership plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 2.2.0.
