This is due to the way iubendaParser::parse_comments() re-processes HTML inside IUB-COOKIE-BLOCK markers through the bundled simple_html_dom parser after WordPress has already KSES-filtered the saved comment: simple_html_dom's remove_noise() stores <code> bodies under a deterministic key ('___noise___ 1000') and restore_noise() later substitutes any matching substring back into attribute values WITHOUT re-escaping, allowing a quote-breaking payload stashed in an allowed <code> element to be injected into an allowed <abbr title=\"___noise___ 1000\"> attribute at render time. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, after an administrator approves the first (otherwise moderated) comment under WordPress's default comment_previously_approved setting."}], "title": "iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more <= 3.13.6 - Unauthenticated Stored Cross-Site Scripting via Comment Content via IUB-COOKIE-BLOCK Marker", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/fc26d5a0-86fc-48b5-af8f-73dd9a7f2b39?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda_cookie_solution.php#L857"}, {"url": "https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/iubenda.class.php#L825"}, {"url": "https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/simple_html_dom.php#L471"}, {"url": "https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/simple_html_dom.php#L2199"}, {"url": "https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/simple_html_dom.php#L2231"}, {"url": "https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda_cookie_solution.php#L832"}, {"url": "https://plugins.trac.wordpress.org/changeset?reponame=&old=3779727%40iubenda-cookie-law-solution&new=3779727%40iubenda-cookie-law-solution"}], "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:N/UI:N/S:C/C:L/I:L/A:N", "baseScore": 7.2, "baseSeverity": "HIGH"}}], "credits": [{"lang": "en", "type": "finder", "value": "Santh"}], "timeline": [{"time": "2026-10-09T18:22:36.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-11-06T13:56:50.000Z", "lang": "en", "value": "Disclosed"}]}}}
