What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Velociraptor's WatchEvent gRPC API can specify the OrgId of the org from which events should be streamed. The server checks the API permissions against the caller's Org instead of the requested Org. This allows a user with API access in one org to read events from another org for which they have no access.
