Apple rushes out emergency fix for screen sharing flaw on Macs - update ASAP
The updates were unexpected. Apple must have considered this flaw serious enough to warrant an immediate fix.
Apple has urgently released security patches for Mac computers to address a critical flaw in the Screen Sharing application. The updates are designed for MacOS Tahoe, Sonoma, and Sequoia operating systems and aim to prevent unauthorized access and control of a Mac via Screen Sharing.
The flaw allows an attacker to bypass the normal requirement for valid credentials when using Screen Sharing, potentially gaining complete control of the affected Mac without authorization. This could enable the attacker to view personal files, manipulate system settings, install malicious software, and even participate in botnet attacks on other computers.
Apple has released three distinct updates for the different MacOS versions: MacOS Tahoe 26.6.1, MacOS Sonoma 14.8.9, and MacOS Sequoia 15.7.9. To install the updates, navigate to System Settings, select General, click Software Update, and then press Update Now to begin the installation process.
While Apple has not reported any known exploits of the vulnerability, the potential for it to be targeted, especially on unprotected networks, is significant. Users are strongly advised to apply the updates as soon as possible to mitigate any risk associated with this security vulnerability.
