### Impact A specially crafted HTTP request can trigger an uncaught exception on the Engine.IO server, thus killing the Node.js process. ``` events.js:292 throw er; // Unhandled 'error' event ^ Error: read ECONNRESET at TCP.onStreamRead (internal/stream_base_commons.js:209:20) Emitted 'error' event on Socket instance at: at emitErrorNT (internal/streams/destroy.js:106:8) at emitErrorCloseNT (internal/streams/destroy.js:74:3) at processTicksAndRejections (internal/process/task_queues.js:80:21) { errno: -104, code: 'ECONNRESET', syscall: 'read' } ``` This impacts all the users of the [`engine.io`](https://www.npmjs.com/package/engine.io) package, including those who uses depending packages like [`socket.io`](https://www.npmjs.com/package/socket.io). ### Patches A fix has been released today (2022/11/20): | Version range | Fixed version | |-------------------|---------------| | `[email protected]` | `3.6.1` | | `[email protected]` | `6.2.1` | For `socket.io` users: | Version range | `engine.io` version | Needs minor update? | |-----------------------------|---------------------|--------------------------------------------------------------------------------------------------------| | `[email protected]` | `~6.2.0` | `npm audit fix` should be sufficient | | `[email protected]` | `~6.1.0` | Please upgrade to `[email protected]` | | `[email protected]` | `~6.0.0` | Please upgrade to `[email protected]` | | `[email protected]` | `~5.2.0` | Please upgrade to `[email protected]` | | `[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` | Please upgrade to `[email protected]` (see [here](https://socket.io/docs/v4/migrating-from-3-x-to-4-0/)) | | `[email protected]` | `~4.0.0` | Please upgrade to `[email protected]` (see [here](https://socket.io/docs/v4/migrating-from-3-x-to-4-0/)) | | `[email protected]` | `~3.6.0` | `npm audit fix` should be sufficient | | `[email protected]` and below | `~3.5.0` | Please upgrade to `[email protected]` | ### 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 [Jonathan Neve](https://github.com/jonathanneve) for the responsible disclosure.
