{"id":"CVE-2026-120540","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-120540","summary":"The iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.13.6.…","details":"The iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.13.6. 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.","published":"2026-11-07T03:17:03.690","modified":"2026-11-07T03:17:03.827","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/iubenda.class.php#L825"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/simple_html_dom.php#L2199"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/simple_html_dom.php#L2231"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda-cookie-class/simple_html_dom.php#L471"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda_cookie_solution.php#L832"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/tags/3.13.5/iubenda_cookie_solution.php#L857"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3779727%40iubenda-cookie-law-solution&new=3779727%40iubenda-cookie-law-solution"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/fc26d5a0-86fc-48b5-af8f-73dd9a7f2b39?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-07T03:17:03.827"}}
