CVE-2026-1304Public exploitNetwork attack vector

Stored script execution via unescaped invoice settings

Published Feb 18, 2026 · Updated Feb 18, 2026

Stored cross-site scripting in Kadence Memberships 3.2.18 and earlier allows remote authenticated users to inject scripts through invoice settings. Multiple invoice fields in core/includes/admin/settings/settings.php store values without sufficient sanitization, while invoice.php renders them without context-appropriate escaping. Administrator access is required, and the stored script executes when another user opens an affected invoice or invoice-settings view.
