A security flaw has been identified in Apple’s macOS operating system. The issue is an improper authentication weakness in the system’s built-in Screen Sharing feature.
This flaw could allow an attacker who is connected to the same network as your macOS device to access Screen Sharing without needing valid login credentials for your device. If you use a Mac to manage your website, access hosting account details, or handle sensitive information related to your site, this could potentially let an unauthorized person view data on your device or take actions on it without your knowledge.
