Bump engine.io and socket.io in /backend

[dependabot]

Bumps engine.io to 3.6.1 and updates ancestor dependency socket.io. These dependencies need to be updated together.

Updates engine.io from 3.4.0 to 3.6.1

Release notes

Sourced from engine.io's releases.

3.6.1

⚠️ 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:

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'
}

Please upgrade as soon as possible.

Bug Fixes

• catch errors when destroying invalid upgrades (83c4071)

3.6.0

Bug Fixes

• add extension in the package.json main entry (#608) (3ad0567)
• do not reset the ping timer after upgrade (1f5d469)

Features

• decrease the default value of maxHttpBufferSize (58e274c)

This change reduces the default value from 100 mb to a more sane 1 mb.

This helps protect the server against denial of service attacks by malicious clients sending huge amounts of data.

• increase the default value of pingTimeout (f55a79a)

Updates socket.io from 2.3.0 to 2.5.0

Release notes

Sourced from socket.io's releases.

2.5.0

⚠️ WARNING ⚠️

The default value of the maxHttpBufferSize option has been decreased from 100 MB to 1 MB, in order to prevent attacks by denial of service.

Security advisory: GHSA-j4f2-536g-r55m

Bug Fixes

• fix race condition in dynamic namespaces (05e1278)
• ignore packet received after disconnection (22d4bdf)
• only set 'connected' to true after middleware execution (226cc16)
• prevent the socket from joining a room after disconnection (f223178)

• ws version: ~7.4.2

2.4.1

This release reverts the breaking change introduced in 2.4.0 (socketio/socket.io@f78a575).

If you are using Socket.IO v2, you should explicitly allow/disallow cross-origin requests:

• without CORS (server and client are served from the same domain):

const io = require("socket.io")(httpServer, {
  allowRequest: (req, callback) => {
    callback(null, req.headers.origin === undefined); // cross-origin requests will not be allowed
  }
});

• with CORS (server and client are served from distinct domains):

io.origins(["http://localhost:3000"]); // for local development
io.origins(["https://example.com"]);

In any case, please consider upgrading to Socket.IO v3, where this security issue is now fixed (CORS is disabled by default).

Reverts

• fix(security): do not allow all origins by default (a169050)
