This flaw could enable non-admin users to invoke arbitrary services, modify configuration files, and access sensitive data, jeopardizing the confidentiality, integrity, and availability of the Home Assistant environment. Home Assistant administrators should prioritize upgrading to version 2.5.2 to mitigate these risks.

Original NVD Description
Blueprint Studio is a VS Code-like file editor for Home Assistant configuration files. Prior to 2.5.2, Blueprint Studio exposed administrator-intended backend API actions to any authenticated Home Assistant user because the backend did not consistently enforce the panel's admin-only authorization boundary. Affected surfaces included the backend API, upload API, stream routes, terminal WebSocket, Blueprint Studio WebSocket subscriptions, call_service, render_template, global_replace, file and stream access paths, upload handling, and terminal helpers. A non-admin user could invoke arbitrary Home Assistant services, expose Home Assistant state through templates, modify configuration files, access streamed or downloaded configuration content, upload files, or reach terminal-related helpers. These actions could compromise the confidentiality, integrity, and availability of the Home Assistant installation. This issue is fixed in version 2.5.2.
