## Affected

- ChurchCRM CRM: fixed in 7.1.0

## Description

ChurchCRM is an open-source church management system. Prior to 7.1.0, he FindFundRaiser.php endpoint reflects user-supplied input (DateStart and DateEnd) into HTML input field attributes without proper output encoding for the HTML attribute context. An authenticated attacker can craft a malicious URL that executes arbitrary JavaScript when visited by another authenticated user. This constitutes a reflected XSS vulnerability. This vulnerability is fixed in 7.1.0.
