CVE-2026-54465

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.1, when websocket-driver is used to implement a WebSocket server on top of a TCP server using WebSocket::Driver.server() or to complement a WebSocket client, a peer can make a single connection consume an unbounded amount of memory by sending an HTTP request or response with a never-ending list of headers. This can lead to the receiving process running out of memory. This issue is fixed in version 0.8.1.

Summary		(es) websocket-driver es un gestor del protocolo WebSocket con E/S conectable. Antes de la versión 0.8.1, cuando websocket-driver se utiliza para implementar un servidor WebSocket sobre un servidor TCP utilizando WebSocket::Driver.server() o para complementar un cliente WebSocket, un par puede hacer que una única conexión consuma una cantidad ilimitada de memoria enviando una solicitud o respuesta HTTP con una lista interminable de encabezados. Esto puede provocar que el proceso receptor se quede sin memoria. Este problema está solucionado en la versión 0.8.1.
