Missing authorization in the OcrModelRight create and delete views in Scripta eScriptorium through 26.04.1 allows a remote authenticated user to grant themselves access to another user's private OCR model and to revoke any user's OCR model access via a POST request, because the ownership check is placed in get_context_data() and therefore runs only on the GET rendering path
