What is CVE-2023-48311?

The DockerSpawner component of JupyterHub allows users to create single-user servers in Docker containers. A configuration oversight was identified in versions starting from 0.11.0, which could let users launch any Docker image instead of limiting them to a specific, approved image. This situation arises when the 'DockerSpawner.allowed_images' configuration is left unspecified. To mitigate the risk, it’s essential for users to either upgrade to DockerSpawner version 13 or later or explicitly define 'DockerSpawner.allowed_images' with a non-empty array containing only the desired image. This update ensures that deployments retain their intended security practices by restricting which images can be utilized.

Affected Version(s)

dockerspawner >= 0.11.0, < 13.0
