This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","score":6.4,"severity":"medium","published":"2026-11-04T09:26:06.627Z","modified":"2026-11-04T20:14:23.468Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"elliotvs","name":"Simple CAPTCHA with Cloudflare Turnstile","platforms":[],"versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.44.3","versionType":"semver"}],"defaultStatus":"unaffected","cpes":[],"source":"Wordfence","url":"https://www.cve.org/CVERecord?id=CVE-2026-93900"}],"remediation":[],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/056a6984-4753-4f52-87b0-1a3cc2f5bde2?source=cve","https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.43.1/inc/integrations/forms/gravity-forms.php#L22","https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.43.1/inc/integrations/forms/gravity-forms.php#L13","https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.41.0/inc/integrations/forms/gravity-forms.php#L22","https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.41.0/inc/integrations/forms/gravity-forms.php#L13","https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/","https://plugins.trac.wordpress.org/changeset/3776057/simple-cloudflare-turnstile/trunk/inc/integrations/forms/gravity-forms.php"],"sources":[{"name":"CVE","id":"CVE-2026-93900","modified":"2026-11-04T20:14:23.468Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-93900"}],"assessments":[{"source":"Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4}],"sourceAffected":[],"observedAt":"2026-11-04T21:12:45.862Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T23:25:34.978Z"},"coverage":[{"source":"NVD","status":"no-result","checkedAt":"2026-11-04T09:40:44.423Z","attemptedAt":"2026-11-04T09:40:44.423Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-11-04T09:40:44.249Z","attemptedAt":"2026-11-04T09:40:44.249Z"},{"source":"EUVD","status":"no-result","checkedAt":"2026-11-04T09:40:43.670Z","attemptedAt":"2026-11-04T09:40:43.670Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-11-04T09:40:44.692Z","attemptedAt":"2026-11-04T09:40:44.692Z"}],"evidence":[],"aiSummary":{"text":"The Simple CAPTCHA with Cloudflare Turnstile WordPress plugin, versions up to 1.44.3, has a Stored Cross-Site Scripting vulnerability via the 'id' attribute of the shortcode.
