CVE-2026-61666

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.2, WebSocket::Driver.server() passes a malformed Host header to URI.parse in lib/websocket/http/request.rb without catching URI::InvalidURIError, allowing a remote client to crash a TCP-backed WebSocket server when the application does not catch the error from parse(). This issue is fixed in version 0.8.2.

Summary		(es) websocket-driver es un gestor del protocolo WebSocket con E/S conectable. Antes de la versión 0.8.2, WebSocket::Driver.server() pasa una cabecera Host malformada a URI.parse en lib/websocket/http/request.rb sin capturar URI::InvalidURIError, lo que permite a un cliente remoto colapsar un servidor WebSocket basado en TCP cuando la aplicación no captura el error de parse(). Este problema se ha corregido en la versión 0.8.2.
