Node.js Adapter for Hono: Unauthenticated memory-leak DoS via aborted WebSocket handshake

GHSA-9mqv-5hh9-4cgg

More information

Details

Summary

A WebSocket upgrade request to an upgradeWebSocket route with a missing or malformed Sec-WebSocket-Key header leaks memory permanently. The request's IncomingMessage is retained in an internal map and a pending promise is never settled, even though no connection is established. Since the route is reachable pre-handshake without authentication, an unauthenticated attacker can flood it to gradually exhaust memory.

Details

The built-in WebSocket helper cleans up its internal map only on a successful handshake or when the route guard rejects the request. When ws aborts the handshake because Sec-WebSocket-Key is missing or malformed, no connection event is emitted, so neither cleanup path runs and the entry is retained forever. A present-but-malformed key leaks identically, so a proxy that only checks for the header's presence does not mitigate it.

Impact

An unauthenticated attacker can flood any public upgradeWebSocket route with malformed-key upgrade requests, causing unbounded memory growth and eventual loss of availability. No confidentiality or integrity impact.

Security fixes

This release includes a fix for the following security issue:

Unauthenticated memory-leak DoS via aborted WebSocket handshake

Affects: upgradeWebSocket. A WebSocket upgrade request with a missing or malformed Sec-WebSocket-Key header leaked the request's IncomingMessage and left a promise pending, even though no connection was established. Since the route is reachable pre-handshake without authentication, an attacker could flood it to gradually exhaust memory. GHSA-9mqv-5hh9-4cgg
