Blueprint Studio is a VS Code-like file editor for Home Assistant configuration files. Prior to 2.5.2, Blueprint Studio backend API handlers in custom_components/blueprint_studio/backend/api.py returned raw exception strings to authenticated Home Assistant users. Some exception messages could contain internal filesystem paths or implementation details. The disclosed information could help an authenticated user fingerprint a Home Assistant installation and refine follow-up attacks. This issue is fixed in version 2.5.2.
