CVE-2026-62389

CVE-2026-62389 affects the ws library (before 8.21.1). The root cause is a memory exhaustion condition in lib/receiver.js where the fragment guard only triggers at maxFragments, allowing an attacker to exhaust heap memory by sending incomplete fragmented WebSocket messages (text frame FIN=0 plus ...

undici: undici: Denial of Service due to unbounded memory growth via WebSocket frames

A flaw was found in undici. A malicious WebSocket server can exploit this by streaming numerous small or empty continuation frames. This can bypass per-frame and cumulative-size validation, leading to unbounded memory growth in the client process. The primary consequence is memory exhaustion,...
