This is due to the plugin calling html_entity_decode() on post_content during rendering in the set_display_variables() function (View.FAQ.class.php, line 746), which converts HTML entity-encoded payloads back into executable HTML, combined with insufficient output escaping in the faq-answer.php template where the decoded content is echoed without wp_kses_post() or any other sanitization. The ufaq custom post type is registered with 'show_in_rest' => true and defaults to 'post' capability_type, allowing Author-level users to create and publish FAQs via the REST API. An Author can submit entity-encoded malicious HTML (e.g., <img src=x onerror=alert()>) which bypasses WordPress's kses sanitization at save time (since kses sees entities as plain text, not tags), but is then decoded back into executable HTML by html_entity_decode() at render time. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in FAQ pages that will execute whenever a user accesses an injected FAQ, either directly or via the [ultimate-faqs] shortcode."}],"id":"CVE-2026-4336","lastModified":"2026-06-17T10:56:26.447","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":6.4,"baseSeverity":"MEDIUM","confidentialityImpact":"LOW","integrityImpact":"LOW","privilegesRequired":"LOW","scope":"CHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"exploitabilityScore":3.1,"impactScore":2.7,"source":"security@wordfence.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-4336","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","timestamp":"2026-04-09T12:58:39.403559Z","version":"2.0.3"}}]},"published":"2026-04-09T05:16:04.910","references":[{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/ultimate-faqs/tags/2.4.7/ewd-ufaq-templates/faq-answer.php#L2"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/ultimate-faqs/tags/2.4.7/includes/CustomPostTypes.class.php#L84"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/ultimate-faqs/tags/2.4.7/views/View.FAQ.class.php#L746"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/ultimate-faqs/trunk/ewd-ufaq-templates/faq-answer.php#L2"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/ultimate-faqs/trunk/includes/CustomPostTypes.class.php#L84"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/ultimate-faqs/trunk/views/View.FAQ.class.php#L746"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3492083%40ultimate-faqs&new=3492083%40ultimate-faqs&sfp_email=&sfph_mail="},{"source":"security@wordfence.com","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/5ac3ac02-d496-46cb-9aff-ffeeb8fd80fa?source=cve"}],"sourceIdentifier":"security@wordfence.com","vulnStatus":"Deferred","weaknesses":[{"description":[{"lang":"en","value":"CWE-79"}],"source":"security@wordfence.com","type":"Secondary"}]}
