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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.2,"severity":"high","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1794018558670,"publishedAt":1794018558670,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/fc26d5a0-86fc-48b5-af8f-73dd9a7f2b39?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda_cookie_solution.php#L857"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/iubenda.class.php#L825"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/simple_html_dom.php#L471"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/simple_html_dom.php#L2199"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/simple_html_dom.php#L2231"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda_cookie_solution.php#L832"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3779727%40iubenda-cookie-law-solution&new=3779727%40iubenda-cookie-law-solution"}],"remediation":[],"revision":"53a187854e7e20747b41d3a7ea04ae01c8c28407446560ac57affbfe293f869d","sources":[{"modifiedAt":1794018558670,"name":"CNA: Wordfence","retrievedAt":1794020932267,"url":"https://www.cve.org/CVERecord?id=CVE-2026-120540"}],"ssvc":null,"status":"published","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","updatedAt":1794020932267}
