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 &quot; 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."}], "title": "Cool FormKit Lite <= 2.7.9 - Authenticated (Contributor+) Stored DOM-Based Cross-Site Scripting via Form Field custom_id Parameter", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/94c6ee49-604d-4183-bd47-7ab2732de6b4?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/assets/js/shared/logic-frontend.js#L719"}, {"url": "https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/includes/fields/conditional-fields-trait.php#L753"}, {"url": "https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/includes/fields/conditional-fields-trait.php#L704"}, {"url": "https://plugins.trac.wordpress.org/browser/extensions-for-elementor-form/tags/2.7.9/modules/forms/widgets/cool-form.php#L711"}, {"url": "https://github.com/CoolPluginsTeam/extensions-for-elementor-form/pull/90"}, {"url": "https://plugins.trac.wordpress.org/changeset/3772891/extensions-for-elementor-form/trunk/assets/js/shared/logic-frontend.js"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-79 Improper Neutralization of Input During Web Page Generation", "cweId": "CWE-79", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N", "baseScore": 6.4, "baseSeverity": "MEDIUM"}}], "credits": [{"lang": "en", "type": "finder", "value": "Wordfence PRISM"}], "timeline": [{"time": "2026-10-28T13:25:49.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-10-29T17:03:09.000Z", "lang": "en", "value": "Disclosed"}]}}}
