      "value": "dockerspawner is a tool to spawn JupyterHub single user servers in Docker containers. Users of JupyterHub deployments running DockerSpawner starting with 0.11.0 without specifying `DockerSpawner.allowed_images` configuration allow users to launch _any_ pullable docker image, instead of restricting to only the single configured image, as intended. This issue has been addressed in commit `3ba4b665b` which has been included in dockerspawner release version 13. Users are advised to upgrade. Users unable to upgrade should explicitly set `DockerSpawner.allowed_images` to a non-empty list containing only the default image will result in the intended default behavior."

Los usuarios de implementaciones de JupyterHub que ejecutan DockerSpawner a partir de 0.11.0 sin especificar la configuraci\u00f3n `DockerSpawner.allowed_images` permiten a los usuarios _any_ pullable imagen acoplable extra\u00edble, en lugar de limitarse a una sola imagen configurada, como se pretende. Este problema se solucion\u00f3 en el commit `3ba4b665b` que se incluy\u00f3 en la versi\u00f3n 13 de dockerspawner. Se recomienda a los usuarios que actualicen. Los usuarios que no puedan actualizar deben configurar expl\u00edcitamente `DockerSpawner.allowed_images` en una lista no vac\u00eda que contenga solo la imagen predeterminada, lo que dar\u00e1 como resultado el comportamiento predeterminado previsto."
