CVE-2026-31859: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in craftcms cmsCVE-2026-31859 0 Craft is a content management system (CMS). The fix for CVE-2025-35939 in craftcms/cms introduced a strip_tags() call in src/web/User.php to sanitize return URLs before they are stored in the session. However, strip_tags() only removes HTML tags (angle brackets) -- it does not inspect or filter URL schemes. Payloads like javascript:alert(document.cookie) contain no HTML tags and pass through strip_tags() completely unmodified, enabling reflected XSS when the return URL is rendered in an href attribute. This vulnerability is fixed in 5.9.7 and 4.17.3. Join the discussion | CVE Database V5 | 03/11/2026, 17:37:19 UTC Added: 03/11/2026, 18:46:35 UTC |
