Eventlet is a concurrent networking library for Python. A websocket

highly compressed data frame. A patch in version 0.31.0 restricts websocket
frame to reasonable limits. As a workaround, restricting memory usage via
OS limits would help against overall machine exhaustion, but there is no
workaround to protect Eventlet process (CVE-2021-21419).");
