The vulnerability occurs because the application fails to properly escape IRCv3 \u0026quot;label\u0026quot; tags when echoing them into server replies. On networks with two or more linked servers, an attacker can leverage this flaw to inject arbitrary server-to-server commands that execute with the authority of the server.
