Vendor Workaround
To mitigate this issue, ensure that client mTLS is enabled for the Maestro gRPC broker by configuring the `BrokerClientCAFile` parameter. If the gRPC message broker type is not required, avoid enabling it. If the gRPC broker is in use, a restart or service reload may be required after applying the configuration changes.

| Description | A flaw was found in the maestro gRPC broker. This vulnerability allows a remote attacker, with a valid client certificate, to bypass authentication. This bypass enables the attacker to subscribe to other consumers' event streams, leading to unauthorized information disclosure, or to publish forged agent status, which can compromise data integrity. | |
