CVE-2026-54465

CVE-2026-54465 affects websocket-driver (Ruby) prior to version 0.8.1. A WebSocket server built on top of a TCP server via WebSocket::Driver.server() or a WebSocket client can trigger a memory exhaustion by sending an HTTP request/response with an unbounded, never-ending header list. The issue is...
