{"cve":"CVE-2026-118500","nvd":{"published":"2026-10-30T06:16:47.610","modified":"2026-10-30T06:16:47.610","status":"Received","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://github.com/CoolPluginsTeam/extensions-for-elementor-form/pull/90","https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/assets/js/shared/logic-frontend.js#L719","https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/includes/fields/conditional-fields-trait.php#L704","https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/includes/fields/conditional-fields-trait.php#L753","https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/modules/forms/widgets/cool-form.php#L711"],"products":[],"source":"nvd","synced_at":"2026-10-30T06:36:07.107513002+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
