Summary
Rapid7 Velociraptor versions before 0.77.3 are affected. The WatchEvent gRPC API checks permissions against the caller's organization instead of the requested OrgId, an authorization bypass through a user-controlled key (CWE-639). A user with API access in one organization can stream live events from another organization they have no access to.

Description from the CNA
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.
