Bump ws and engine.io-client by dependabot[bot] · Pull Request #94 · auth0/auth0-guardian.js

dependabot · 2026-05-28T18:43:38Z

Bumps ws and engine.io-client. These dependencies needed to be updated together.
Updates ws from 8.17.1 to 8.20.1

Release notes

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.

8.20.0

Features

Added exports for the PerMessageDeflate class and utilities for the Sec-WebSocket-Extensions and Sec-WebSocket-Protocol headers (d3503c1f).

8.19.0

Features

Added the closeTimeout option (#2308).

Bug fixes

Handled a forthcoming breaking change in Node.js core (19984854).

Updates engine.io-client from 6.6.1 to 6.6.5

Release notes

Sourced from engine.io-client's releases.

engine.io-client@6.6.5

The ws dependency was bumped to ~8.20.1 following CVE-2026-45736.

Note from the ws maintainers:

Although the calculated CVSS severity is medium, the actual severity is believed to be low, as the flaw is only exploitable through misuse that is unlikely in practice.

Medium severity vulnerability may affect your project—review required:
Line 3735 lists a dependency (jsonwebtoken) with a known Medium severity vulnerability.

ℹ️ Why this matters

Affected versions of jsonwebtoken are vulnerable to Improper Authentication. Insecure implementation of key retrieval function could lead to Forgeable Public/Private Tokens from RSA to HMAC.

References: GHSA, CVE

To resolve this comment:
Check if you are using a poorly implemented key retrieval function and your application is supporting usage of both symmetric key and asymmetric key in jwt.verify() implementation with the same key retrieval function..

If you're affected, upgrade this dependency to at least version 9.0.0 at package-lock.json.

High severity vulnerability may affect your project—review required:
Line 43 lists a dependency (acorn) with a known High severity vulnerability.

ℹ️ Why this matters

Affected versions of acorn are vulnerable to Uncontrolled Resource Consumption. A regular-expression denial-of-service exists in Acorn's RegExp parser: a pattern like /[x-\ud800]/u (an invalid UTF-16 range) causes the parser to spin in an infinite loop. If an application feeds untrusted code directly into Acorn, an attacker can supply such a regex to trigger a CPU-hogging infinite loop and achieve Denial of Service.

References: GHSA

To resolve this comment:
Check if you are using acorn on the CLI.

If you're affected, upgrade this dependency to at least version 5.7.4 at package-lock.json.

High severity vulnerability may affect your project—review required:
Line 5314 lists a dependency (tree-kill) with a known High severity vulnerability.

ℹ️ Why this matters

Affected versions of tree-kill are vulnerable to Improper Control of Generation of Code ('Code Injection'). The tree-kill package is vulnerable to command injection on Windows. An attacker can control the unsanitized input passed to the kill function, potentially leading to arbitrary command execution on the host system.

References: GHSA, CVE

To resolve this comment:
Check if you are using tree-kill Command Line Interface in Windows System.

High severity vulnerability may affect your project—review required:
Line 3735 lists a dependency (jsonwebtoken) with a known High severity vulnerability.

ℹ️ Why this matters

Affected versions of jsonwebtoken are vulnerable to Use Of A Broken Or Risky Cryptographic Algorithm. The library could be misconfigured so that legacy, insecure key types are used for signature verification. For example, DSA keys could be used with the RS256 algorithm.

References: GHSA, CVE

To resolve this comment:

Line 2098 lists a dependency (deep-extend) with a known Critical severity vulnerability. Fixing requires upgrading or replacing the dependency.

ℹ️ Why this matters

Affected version of deep-extend is vulnerable to Prototype Pollution. Malicious input passed to deep-extend allows an attacker to overwrite the prototype of Object, polluting all JavaScript objects with arbitrary properties. This can lead to Denial of Service or even Remote Code Execution.
