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"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-30T15:20:48.539470Z","id":"CVE-2026-118500","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-30T15:57:46.333Z"}}]}}
