CVE-2023-25346Public exploitNetwork attack vector

Browser script execution via reflected id parameter

Published Apr 25, 2023 · Updated Feb 3, 2025

Reflected XSS in ChurchCRM 4.5.3 allows remote attackers to execute script in a user’s browser through the id query parameter. The /churchcrm/v2/family/not-found response reflects the id value into generated HTML without neutralizing script-capable input. Exploitation requires a user to open an attacker-crafted URL; script then runs in the ChurchCRM origin and can read or alter browser-accessible data.
