Querybook is a Big Data Querying UI, combining collocated table metadata and a simple notebook interface. Querybooks datadocs functionality works by using a Websocket Server. The client talks to this WSS whenever updating/deleting/reading any cells as well as for watching the live status of query executions. Currently the CORS setting allows all origins, which could result in cross-site websocket hijacking and allow attackers to read/edit/remove datadocs of the user. This issue has been addressed in version 3.32.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
