Name of the Vulnerable Software and Affected Versions: Docker Desktop versions prior to 3.6.0

Description: The issue is related to incorrect access control in Docker Desktop. If a low-privileged account can access the server running the Windows containers, it can lead to a full container compromise in both process isolation and Hyper-V isolation modes. This allows an attacker with low privilege to read, write, and possibly even execute code inside the containers.

Recommendations: For Docker Desktop versions prior to 3.6.0, update to version 3.6.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the server running the Windows containers to prevent low-privileged accounts from accessing it.
