This is due to missing authorization checks on the twiz_ajax_callback AJAX action's 'savesection' handler combined with the use of eval() to execute user-supplied 'custom logic' code on the frontend. The AJAX handler at twiz-ajax.php verifies a nonce but performs no current_user_can() capability check for the ACTION_SAVE_SECTION case. Furthermore, the nonce is exposed to any authenticated user through the directly-accessible twiz-ajax.js.php file which loads WordPress and outputs the nonce. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary PHP code via the twiz_custom_logic POST parameter when saving a section with output choice 'twiz_logic_output'."}],"id":"CVE-2026-4327","lastModified":"2026-09-21T13:33:33.387","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"HIGH","baseScore":8.8,"baseSeverity":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"HIGH","privilegesRequired":"LOW","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"exploitabilityScore":2.8,"impactScore":5.9,"source":"security@wordfence.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-4327","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","timestamp":"2026-09-19T13:23:25.810413Z","version":"2.0.3"}}]},"published":"2026-09-19T08:16:53.887","references":[{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/the-welcomizer/tags/2.8.1/includes/twiz.menu.class.php#L265"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/the-welcomizer/tags/2.8.1/includes/twiz.menu.class.php#L507"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/the-welcomizer/tags/2.8.1/includes/twiz.menu.class.php#L580"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/the-welcomizer/tags/2.8.1/includes/twiz.output.class.php#L828"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/the-welcomizer/tags/2.8.1/twiz-ajax.php#L148"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/the-welcomizer/trunk/includes/twiz.menu.class.php#L265"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/the-welcomizer/trunk/includes/twiz.menu.class.php#L507"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/the-welcomizer/trunk/includes/twiz.menu.class.php#L580"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/the-welcomizer/trunk/includes/twiz.output.class.php#L828"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/the-welcomizer/trunk/twiz-ajax.php#L148"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/log/the-welcomizer/"},{"source":"security@wordfence.com","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/73fb7102-66ff-4309-a98f-bbbfd3ddbba6?source=cve"}],"sourceIdentifier":"security@wordfence.com","vulnStatus":"Deferred","weaknesses":[{"description":[{"lang":"en","value":"CWE-94"}],"source":"security@wordfence.com","type":"Secondary"}]}
