| Doc Text: |
A flaw was found in NATS-Server. A remote attacker, by connecting a leafnode to a NATS-Server, could propagate unchecked identity claims through the `Nats-Request-Info:` message header. This vulnerability allows for the spoofing of client identities, potentially leading to NATS clients making incorrect trust decisions based on misleading information. This could result in unauthorized information disclosure or integrity compromises within the messaging system.
