Overview
Affected versions of this package are vulnerable to Missing Release of Resource after Effective Lifetime in the Server-Sent Events implementation, exploitable via the /stream endpoint. An attacker can cause the server to stop accepting new connections and increase memory consumption by repeatedly connecting and disconnecting.
Workaround
This vulnerability can be avoided by limiting incoming connections, enforcing request timeouts, triggering routine restarts to clean up connections, or dedicate a server to SSE connections so that they cannot interfere with regular API usage.
