This makes it possible for unauthenticated attackers to create a new Administrator-level WordPress account by supplying `wp_capabilities[administrator]=1` alongside standard registration fields. The nonce required by the endpoint is publicly emitted into the `front_end_data` JavaScript object on every front-end page via `wp_enqueue_scripts`, making it trivially obtainable by any unauthenticated visitor before submitting the malicious request.","state":0,"publishedAt":"2026-10-14T07:43:35.763+00:00","modifiedAt":"2026-10-15T16:43:48.707+00:00","affected":[{"ecosystem":"Vendor product","name":"SimpleForm – Form Maker to Chat Apps with Quiz, Poll and Multi Lead Notifications","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wpazleen\",\n                    \"product\": \"SimpleForm – Form Maker to Chat Apps with Quiz, Poll and Multi Lead Notifications\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"3.10.0\",\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:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/b2b973fe-1209-43dc-b2a3-74086b12fe97?source=cve","https://plugins.trac.wordpress.org/browser/simple-form/tags/3.10.0/app/Integrations/WordPressAuth.php#L291","https://plugins.trac.wordpress.org/browser/simple-form/tags/3.10.0/app/Integrations/WordPressAuth.php#L184","https://plugins.trac.wordpress.org/browser/simple-form/tags/3.10.0/app/Integrations/WordPressAuth.php#L32","https://plugins.trac.wordpress.org/browser/simple-form/tags/3.10.0/app/Assets.php#L265","https://plugins.svn.wordpress.org/simple-form/trunk/","https://plugins.trac.wordpress.org/changeset/3726513/simple-form/trunk/app/Integrations/WordPressAuth.php"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104748","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104748","identifiers":["CVE-2026-104748"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
