Until a fix is available, restrict access to the CovenantHub SignalR hub to trusted users and networks to mitigate unauthorized access risks.
Description
Covenant through 0.6 registers the CovenantHub SignalR hub without an Authorize attribute, allowing unauthenticated callers to invoke CreateHttpListener and receive a signed JWT token. Attackers can use the obtained token to authenticate against the entire operator API and access grunts, credentials, binaries, events, and the operator roster.
