CVE-2024-38355

Summary

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 socket.io@4.6.2 (released in May 2023). The fix was backported in the 2.x branch as well with commit d30630ba10.
