描述

### Impact A specially crafted HTTP request can trigger an uncaught exception on the Engine.IO server, thus 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 impacts all the users of the [`engine.io`](https://www.npmjs.com/package/engine.io) package starting from version `4.0.0`, including those who uses depending packages like [`socket.io`](https://www.npmjs.com/package/socket.io). ### Patches A fix has been released for each major branch: | Version range | Fixed version | | --- | --- | | `[email protected]` | `4.1.2` | | `[email protected]` | `5.2.1` | | `[email protected]` | `6.1.1` | Previous versions (`< 4.0.0`) are not impacted. For `socket.io` users: | Version range | `engine.io` version | Needs minor update? | | --- | --- | --- | | `[email protected]` | `~6.1.0` | - | `[email protected]` | `~6.0.0` | Please upgrade to `[email protected]` | `[email protected]` | `~5.2.0` | - | `[email protected]` | `~5.1.1` | Please upgrade to `[email protected]` | `[email protected]` | `~5.0.0` | Please upgrade to `[email protected]` | `[email protected]` | `~4.1.0` | - | `[email protected]` | `~4.0.0` | Please upgrade to `[email protected]` or `[email protected]` (see [here](https://socket.io/docs/v4/migrating-from-3-x-to-4-0/)) In most cases, running `npm audit fix` should be sufficient. You can also use `npm update engine.io --depth=9999`. ### Workarounds There is no known workaround except upgrading to a safe version. ### For more information If you have any questions or comments about this advisory: * Open an issue in [`engine.io`](https://github.com/socketio/engine.io) Thanks to Marcus Wejderot from Mevisio for the responsible disclosure.
