Ocho de esos puntos finales (list, create, get, update, delete, test, listBranches, browseFiles) nunca llaman a la funci\u00f3n auxiliar checkAdmin(ctx) que utiliza cualquier otro recurso gestionado por el administrador (registros de contenedores, entornos, usuarios, claves de API, swarm, configuraciones, sistema, notificaciones, eventos), y el middleware de autenticaci\u00f3n de huma aplica deliberadamente solo la autenticaci\u00f3n, no el rol de administrador. Como resultado, cualquier usuario con sesi\u00f3n iniciada con el rol de usuario predeterminado puede listar, crear, modificar, eliminar y probar configuraciones de repositorios git. Al redirigir la URL de un repositorio existente a un host controlado por un atacante, omitiendo los campos token/sshKey (que UpdateRepository solo reescribe cuando se suministran expl\u00edcitamente), el atacante provoca que Arcane descifre la clave PAT/SSH leg\u00edtima en su siguiente llamada a /test, /branches o /files y la presente como autenticaci\u00f3n b\u00e1sica HTTP (o autenticaci\u00f3n por clave SSH) al host del atacante, produciendo una exfiltraci\u00f3n en un solo paso de credenciales Git en texto plano.
