{"schema":"threatline.record/2","record":{"id":"CVE-2026-19652","aliases":[],"summary":"Divi Membership <= 2.2.0 - Unauthenticated Privilege Escalation via 'form_id' Parameter","details":"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.","categories":["Unclassified"],"product":"Divi Membership","vendor":"DiviEngine","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-19652","source_modified_at":"2026-10-03T15:42:47.812Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Divi Membership","vendor":"DiviEngine","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.2.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":9.8,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00333,"percentile":0.25298,"score_date":"2026-10-23"},"published_at":"2026-10-02T13:29:05.573Z","modified_at":"2026-10-03T15:42:47.812Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-19652","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-03T15:42:47.812Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-19652","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/81d46c7a-dfe4-4991-99cc-66e5c6d3e3c8?source=cve"},{"source":"CVE List","url":"https://diviengine.com/product/divi-membership/"},{"source":"CVE List","url":"https://diviengine.com/divi-membership-changelog/"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"total","assessed_at":"2026-10-03T15:34:56.946257Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-03T15:42:47.812Z","content_hash":"b2ea018426ae678f661bcc35d3461df6bbc126f50eb2110f6cf9214574b9fddf"}}
