6.1.1

⚠️ This release contains an important security fix ⚠️

A malicious client could send a specially crafted HTTP request, triggering an uncaught exception and killing the Node.js process:

RangeError: Invalid WebSocket frame: RSV2 and RSV3 must be clear at Receiver.getInfo (/.../node_modules/ws/lib/receiver.js:176:14) at Receiver.startLoop (/.../node_modules/ws/lib/receiver.js:136:22) at Receiver._write (/.../node_modules/ws/lib/receiver.js:83:10) at writeOrBuffer (internal/streams/writable.js:358:12)

This bug was introduced by this commit, included in engine.io@4.0.0, so previous releases are not impacted.

Thanks to Marcus Wejderot from Mevisio for the responsible disclosure.
