Docker Desktop for macOS Vulnerability

A security flaw labeled CVE-2025-4095 has been identified in Docker Desktop for macOS, affecting the Registry Access Management (RAM) system. This vulnerability allows users to pull down unauthorized images from registries when a macOS configuration profile enforces organizational sign-in, bypassing intended access restrictions.

Impact:

• Severity: Medium
• Risk: Potential for disruption of communications or business operations due to the installation of malicious container images.

Resolution:

• Docker has released a fix in version 4.41 of Docker Desktop, which is now available for download.
• Administrators are advised to update affected installations to mitigate the risk.

What is Docker?

• Docker is a popular tool for developing and deploying applications using containers. Containers bundle development environments, build systems, applications, and deployment information into a single file, known as an 'image.'
• Registries: Central locations where container images are stored, such as DockerHub, Amazon ECR, Google, and Microsoft Azure.
• Docker Desktop for macOS: An application that helps users manage and download container images on their Macs, including logging into registries using defined credentials.
