Stored XSS via crafted CSV import

Published Feb 9, 2023 · Updated Mar 24, 2025

Stored cross-site scripting in ChurchCRM 4.5.3 and earlier allows remote authenticated users to run scripts via a crafted CSV import. The disclosure identifies the CSV Import function but does not reveal which imported field stores the payload or which page renders it without encoding. Administrative privileges and another user's interaction are required; the public record does not establish native-code execution or service interruption.
