This is due to missing nonce validation in the plugin's settings page handler (admin/setting.php). The settings form does not include a wp_nonce_field() and the form processing code does not call wp_verify_nonce() or check_admin_referer() before saving settings to the database via $wpdb->update(). This makes it possible for unauthenticated attackers to modify the plugin's CAPTCHA settings (enabling or disabling CAPTCHA on login, registration, lost password, and comment forms) via a forged request, granted they can trick a site administrator into performing an action such as clicking a link."}],"id":"CVE-2026-4121","lastModified":"2026-06-17T10:56:01.560","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":4.3,"baseSeverity":"MEDIUM","confidentialityImpact":"NONE","integrityImpact":"LOW","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"REQUIRED","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"exploitabilityScore":2.8,"impactScore":1.4,"source":"security@wordfence.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-4121","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","timestamp":"2026-04-23T13:46:48.672016Z","version":"2.0.3"}}]},"published":"2026-04-22T09:16:23.490","references":[{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/kcaptcha/tags/1.0.1/admin/setting.php#L12"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/kcaptcha/tags/1.0.1/admin/setting.php#L30"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/kcaptcha/tags/1.0.1/admin/setting.php#L47"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/kcaptcha/trunk/admin/setting.php#L12"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/kcaptcha/trunk/admin/setting.php#L30"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/kcaptcha/trunk/admin/setting.php#L47"},{"source":"security@wordfence.com","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/a6c1c73b-76e3-4cb9-ad53-9d5d4e7519c9?source=cve"}],"sourceIdentifier":"security@wordfence.com","vulnStatus":"Deferred","weaknesses":[{"description":[{"lang":"en","value":"CWE-352"}],"source":"security@wordfence.com","type":"Secondary"}]}
