What happened
In a hardened Docker environment, with Enhanced Container Isolation ( ECI https://docs.docker.com/enterprise/security/hardened-desktop/enhanced-container-isolation/ ) enabled, an administrator can utilize the command restrictions feature https://docs.docker.com/enterprise/security/hardened-desktop/enhanced-container-isolation/config/#command-restrictions to restrict commands that a container with a Docker socket mount may issue on that socket. Due to a software bug, the configuration to restrict commands was ignored when passed to ECI, allowing any command to be executed on the socket. This grants excessive privileges by permitting unrestricted access to powerful Docker commands. The vulnerability affects only Docker Desktop 4.46.0 users that have ECI enabled and are using the Docker socket command restrictions feature. In addition, since ECI restricts mounting the Docker socket into containers by default, it only affects containers which are explicitly allowed by the administrator to mount the Docker socket.
