In Docker Desktop before v4.29.0, an attacker who has gained access to the Docker Desktop VM through a container breakout can further escape to the host by passing extensions and dashboard related IPC messages.
Docker Desktop v4.29.0 https://docs.docker.com/desktop/release-notes/#4290 fixes the issue on MacOS, Linux and Windows with Hyper-V backend.
As exploitation requires Allow only extensions distributed through the Docker Marketplace to be disabled, Docker Desktop v4.31.0 https://docs.docker.com/desktop/release-notes/#4310 additionally changes the default configuration to enable this setting by default.
