The 5.0.3 patch introduced a wp_hash()/hash_equals() signature gate on the pt-paytium-user-data field, but left a second filter — pt_cf_checkout_meta(), registered on the pt_meta_values hook after the signed builder — that copies every $_POST['pt_form_field'][*] key verbatim into the payment meta array without any signature verification; this allows the pt-user-role value it copies to overwrite the signed path's output, after which paytium_user_data_processing() reads the persisted _pt-user-role post meta and passes it directly as the role argument to wp_insert_user(). This makes it possible for unauthenticated attackers to register a new WordPress account with the administrator role and fully take over the site. Exploitation requires submitting a payment through a publicly-exposed [paytium] shortcode form and completing the resulting payment flow, after which the attacker can seize the new administrator account via the standard lost-password flow on their supplied email address.","state":0,"publishedAt":"2026-09-24T01:27:57.343+00:00","modifiedAt":"2026-09-24T15:04:13.676+00:00","affected":[{"ecosystem":"Vendor product","name":"Paytium: Mollie payment forms & donations","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"paytiumsupport\",\n                    \"product\": \"Paytium: Mollie payment forms & donations\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"5.0.3\",\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/caa1a42a-6bb2-42c8-aae7-fb1c895573a8?source=cve","https://plugins.trac.wordpress.org/browser/paytium/tags/5.0.3/includes/user-data-functions.php#L214","https://plugins.trac.wordpress.org/browser/paytium/tags/5.0.3/includes/process-payment-functions.php#L1103","https://plugins.trac.wordpress.org/browser/paytium/tags/5.0.3/includes/process-payment-functions.php#L696","https://plugins.trac.wordpress.org/browser/paytium/tags/5.0.3/includes/process-payment-functions.php#L21","https://plugins.trac.wordpress.org/browser/paytium/tags/5.0.3/includes/payment-functions.php#L113","https://plugins.trac.wordpress.org/changeset/3678569/paytium"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-18467","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-18467","identifiers":["CVE-2026-18467"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
