CVE-2026-45626

Arcane is an interface for managing Docker containers, images, networks, and volumes. In 1.18.1 and earlier, GET /environments/{id}/volumes/{volumeName}/browse accepts a path query parameter that is passed to a shell command (sh -c "find … | while …") inside an Arcane helper container. The path sanitiser blocks ../ traversal but does not strip Bourne-shell metacharacters such as $() or backticks, and strconv.Quote only escapes Go string metacharacters, not shell substitution sequences. Any authenticated user with access to a browseable volume can execute arbitrary commands inside the helper container; command output is reflected back in the 500 error body.

Summary		(es) Arcane es una interfaz para gestionar contenedores Docker, imágenes, redes y volúmenes. En 1.18.1 y versiones anteriores, GET /environments/{id}/volumes/{volumeName}/browse acepta un parámetro de consulta de ruta que se pasa a un comando de shell (sh -c 'find … \| while …') dentro de un contenedor auxiliar de Arcane. El saneador de rutas bloquea el recorrido ../ pero no elimina los metacaracteres de Bourne-shell como $() o las comillas invertidas, y strconv.Quote solo escapa los metacaracteres de cadena de Go, no las secuencias de sustitución de shell. Cualquier usuario autenticado con acceso a un volumen navegable puede ejecutar comandos arbitrarios dentro del contenedor auxiliar; la salida del comando se refleja en el cuerpo del error 500.
