CVE-2023-27059Network attack vector

Script execution via unescaped group name

Published Mar 16, 2023 · Updated Feb 26, 2025

Stored XSS in the Edit Group function of ChurchCRM 4.5.3 allows remote authenticated users to execute scripts through a group name. The workflow accepts a crafted Edit Group Name value without neutralizing script or HTML markup before the value is rendered in a page. Low-privileged access is required to save the name, and another user must view the affected page; execution is confined to that viewer’s browser context.
