CVE-2026-84260Network attack vector

Unauthenticated stored XSS via unescaped admin-page content

Published Oct 11, 2026 · Updated Oct 11, 2026

Stored XSS in click5 CRM add-on to Gravity Forms 1.0.3 and earlier allows remote attackers to inject scripts via an unauthenticated endpoint. The plugin outputs submitted content in an admin page without sanitizing and escaping it, treating attacker-controlled content as executable markup. Exploitation requires an administrator or another privileged user to view that page, executing scripts in that user's browser session rather than directly executing server-side code.
