Browser-session compromise via stored deposit-field XSS
Published Aug 11, 2023 · Updated Oct 9, 2024
Stored cross-site scripting in ChurchCRM 4.2.1 allows remote authenticated users to execute script in another user’s browser via a deposit field. The Add New Deposit field stores a crafted payload that the View All Deposit module later renders without neutralizing executable browser content. A low-privileged account and user interaction are required; exploitation exposes data available to the viewing user and permits actions in that user’s session.
