CVE-2026-32424Network attack vector

Browser script execution via unescaped client output

Published Mar 13, 2026 · Updated Mar 13, 2026

Stored XSS in BoldGrid Sprout Clients 3.2.2 and earlier allows remote authenticated users to execute scripts through client data. The plugin stores contributor-supplied client data and renders it without sufficient output escaping, causing embedded script to run in a visitor's browser. Contributor-level access is required to plant the payload, and exploitation requires another user to view the affected client output.
