CVE-2026-44985

Estado: AnalizadaAlta (8.7)—

Dozzle is a realtime log viewer for docker containers. Prior to 10.5.2, he WebSocket upgrader for the /exec and /attach endpoints uses CheckOrigin: func(r *http.Request) bool { return true }, accepting upgrade requests from any origin. Combined with the JWT cookie using SameSite: Lax, this enables Cross-Site WebSocket Hijacking (CSWSH). An attacker hosting a page on a same-site origin (e.g., a sibling subdomain, or another service on localhost) can initiate a WebSocket connection to the exec endpoint that carries the victim's valid JWT cookie, gaining interactive shell access in any container the victim is authorized to access. This vulnerability is fixed in 10.5.2.

Combinado con la cookie JWT que utiliza SameSite: Lax, esto permite el Secuestro de WebSocket entre sitios (CSWSH). Un atacante que aloja una página en un origen del mismo sitio (por ejemplo, un subdominio hermano, u otro servicio en localhost) puede iniciar una conexión WebSocket al punto final exec que lleva la cookie JWT válida de la víctima, obteniendo acceso interactivo a la shell en cualquier contenedor al que la víctima esté autorizada a acceder.
