CVE-2026-110631
Komodo hasta la versión 2.3.3 contiene una vulnerabilidad de omisión de autenticación en el agente Periphery que permite a atacantes no autenticados conectarse como un Core de confianza, porque las listas vacías core_public_keys y passkeys fallan en modo abierto por defecto. Los atacantes que alcancen el puerto 8120 pueden presentar cualquier par de claves generado para emitir solicitudes a la API de Periphery, incluidas sesiones de terminal y operaciones de contenedores, ejecutando comandos en los hosts gestionados, normalmente como root.
