Critical Docker Sandboxes Flaw Lets Malicious Guest Code Read and Modify macOS Host Files

Docker Sandboxes runs each AI coding agent in its own small virtual machine with the project directory shared in. The code that could escape is whatever runs inside that machine, such as a coding agent that has been turned against its user, or anything malicious the agent installs and runs.

Docker has not reported any exploitation. CISA’s added assessment on the CVE record lists exploitation as none, and the flaw is not in CISA’s Known Exploited Vulnerabilities catalog as of the catalog version released on September 16.

The flaw needs malicious code inside the sandbox, and protecting the host from what an agent runs is what the sandbox is for. The agent installs packages and runs commands with sudo inside the virtual machine, and Docker’s isolation documentation says the hypervisor boundary “is the isolation control, not in-VM privilege separation.”
