Socket.IO is an open source, real-time, bidirectional, event-based, communication framework. A specially crafted Socket.IO packet can trigger an uncaught exception on the Socket.IO server, thus killing the Node.js process. This issue is fixed by commit 15af22fc22
which has been included in [email protected]
(released in May 2023). The fix was backported in the 2.x branch as well with commit d30630ba10
. Users are advised to upgrade. Users unable to upgrade may attach a listener for the “error” event to catch these errors.
