CVE-2026-23970Network attack vector

Unauthenticated stored cross-site scripting

Published Jun 15, 2026 · Updated Jun 15, 2026

Stored cross-site scripting in Themeisle Redirection for Contact Form 7 3.2.8 and earlier allows remote attackers to run script in visitors' browsers. Published sources identify stored XSS but do not disclose the affected parameter, handler, or missing output-encoding operation. No account is required, but exploitation requires a user to view the stored payload; script executes in the affected site's origin and can alter displayed content or access browser-visible data.
