CVE-2023-24690Network attack vector

Account takeover via stored family-registration script injection

Published Feb 9, 2023 · Updated Mar 24, 2025

Stored XSS in ChurchCRM 4.5.3 and earlier allows remote authenticated users to execute scripts through crafted family-registration data. The /api/public/register/family handler persists a crafted payload that later renders as executable script or HTML; the public evidence does not identify the parameter or output sink. A privileged user must view the stored data, exposing that browser session to cookie theft and account takeover.
