{"id":"CVE-2026-118500","published":"2026-10-30T06:16:47.610","lastModified":"2026-10-30T06:16:47.610","description":"The Cool FormKit Lite – Advanced Form Builder for Elementor plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the '_elementor_data.form_fields[].custom_id' parameter in all versions up to, and including, 2.7.9 due to insufficient input sanitization and output escaping. 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. The esc_html() call applied at server emission is bypassed because the HTML fragment-serialization algorithm restores " to a raw double-quote inside text nodes when jQuery .html() extracts the template, allowing the attacker-controlled custom_id to break out of an HTML attribute context within the plugin's own frontend script.","cvssScore":6.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/CoolPluginsTeam/extensions-for-elementor-form/pull/90","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/assets/js/shared/logic-frontend.js#L719","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/includes/fields/conditional-fields-trait.php#L704","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/includes/fields/conditional-fields-trait.php#L753","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/modules/forms/widgets/cool-form.php#L711","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3772891/extensions-for-elementor-form/trunk/assets/js/shared/logic-frontend.js","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/94c6ee49-604d-4183-bd47-7ab2732de6b4?source=cve","tags":[]}],"exploitRefs":[{"url":"https://github.com/CoolPluginsTeam/extensions-for-elementor-form/pull/90","tags":[]}],"hasPoc":true,"ai":null}
