Severity
Summary
An input validation vulnerability exists in an API component of the orchestrator. An authenticated user can exploit this flaw to manipulate backend queries, which may result in unauthorized access to data beyond their intended privileges and cause the underlying system to initiate unintended outbound network connections.
This issue was discovered internally by Arista and the company is not aware of any malicious uses of this issue in customer networks.
