A Backdoor in Plain Sight: The macOS Screen Sharing Flaw A recent patch from Apple has addressed a critical vulnerability in macOS screen sharing that allows an attacker to initiate screen sharing without valid credentials.
This flaw could grant remote access to your computer, enabling the attacker to view your screen, open apps or files, and perform other actions.
The fact that Apple deemed this issue serious enough to push out updates for three different versions of macOS – Sonoma 14. 8. 9, Sequoia 15. 7. 9, and Tahoe 26. 6. 1 – underscores the severity of the problem.
