This makes it possible for unauthenticated attackers to extract arbitrary WordPress post meta values — including license keys, API tokens, SMTP credentials, and Stripe or AWS secrets stored on any post type — via form submission notification emails or stored entries. The submission nonce is publicly rendered in every embedded form and can additionally be minted anonymously via the nopriv everest_forms_get_form_update_nonce action, meaning no account or prior authentication of any kind is required to complete the exploit.","state":0,"publishedAt":"2026-10-29T09:25:36.385+00:00","modifiedAt":"2026-10-29T10:45:40.641+00:00","affected":[{"ecosystem":"Vendor product","name":"Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder with AI","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wpeverest\",\n                    \"product\": \"Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder with AI\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"3.6.2\",\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:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/b820a342-3aaa-4782-9d82-afe53028b72c?source=cve","https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.1/includes/class-evf-smart-tags.php#L503","https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.1/includes/class-evf-form-task.php#L731","https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.1/includes/class-evf-form-task.php#L261","https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.1/includes/class-evf-ajax.php#L681","https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.1/includes/class-evf-ajax.php#L2342","https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.1/includes/shortcodes/class-evf-shortcode-form.php#L370","https://github.com/themegrill/everest-forms/pull/1669/changes","https://plugins.trac.wordpress.org/changeset/3747723/everest-forms/trunk/includes/class-evf-form-task.php"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-91153","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-91153","identifiers":["CVE-2026-91153"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
