InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A Stored Cross-Site Scripting (XSS) vulnerability exists in InvoicePlane (latest version) that allows an authenticated user with permissions to manage Invoice Groups to inject malicious JavaScript into the "Identifier Format" field. This script executes when any user views the invoice list or the main dashboard. Version 1.7.1 patches the issue.
