A security issue has been found in Elasticsearch versions from 7.13.0 through 7.14.0. An issue was found with how API keys are created with the fleet-server service account. When an API key is created with a service account, it is possible that the API key could be created with higher privileges than intended. Using this vulnerability, a compromised fleet-server service account could escalate themselves to a super-user.
