chore(deps): bump ws from 8.18.3 to 8.20.1

[dependabot]

Bumps ws from 8.18.3 to 8.20.1.

Release notes

Sourced from ws's releases.

8.20.1

Bug fixes

• Fixed an uninitialized memory disclosure issue in websocket.close() (c0327ec1).

Providing a TypedArray (e.g. Float32Array) as the reason argument for websocket.close(), rather than the supported string or Buffer types, caused uninitialized memory to be disclosed to the remote peer.

import { deepStrictEqual } from 'node:assert';
import { WebSocket, WebSocketServer } from 'ws';
const wss = new WebSocketServer(
{ port: 0, skipUTF8Validation: true },
function () {
const { port } = wss.address();
const ws = new WebSocket(ws://localhost:${port}, {
skipUTF8Validation: true
});
ws.on('close', function (code, reason) {
  deepStrictEqual(reason, Buffer.alloc(80));
});

}
);
wss.on('connection', function (ws) {
ws.close(1000, new Float32Array(20));
});

The issue was privately reported by Nikita Skovoroda.

PR Review

✅ No critical issues found.

Dependabot bump of ws from 8.18.3 → 8.20.1 (yarn.lock only). 8.20.1 includes a security fix for an uninitialized memory disclosure in websocket.close() when a TypedArray is passed as the close reason. Safe patch-level upgrade with no API changes.

[github-actions]

<!-- deep-review -->

Deep Review

Single-file yarn.lock change: bumps the ws@npm:^8.18.0 resolution from 8.18.3 to 8.20.1. The bump is motivated by the 8.20.1 upstream security fix (uninitialized memory disclosure in websocket.close() when callers pass a TypedArray as the reason argument). ws is purely transitive here — no package.json declares it directly; three parent packages pin ws: "npm:^8.18.0", and 8.20.1 satisfies that range. The unrelated ws@npm:^7 resolution (7.5.10) is untouched, so blast radius is contained to the one updated entry.

✅ No critical issues found.

The intermediate 8.19.0 and 8.20.0 releases are additive (closeTimeout option; PerMessageDeflate and header-utility exports); they do not change the WebSocket API surface the codebase already consumes. No executable code, tests, configuration, CI, or schema are touched by this diff, so the persona reviewers (correctness, testing, maintainability, project-standards, security, etc.) would have no behavior surface to inspect — nothing to flag.

---

Reviewers (1): orchestrator only (3-line yarn.lock-only diff with no semver-range change and no executable code — persona sub-agents not dispatched).
