Apple has issued a critical warning to all MacBook and Mac users across the globe, urging them to promptly update their macOS software. The recent launch of macOS Sequoia version 15.1.1 addresses significant security vulnerabilities that could impact millions.
The update, part of Apple’s ongoing commitment to user safety, was announced following a keynote by CEO Tim Cook in Brooklyn. The latest patch corrects flaws within JavaScriptCore and WebKit—both essential components of the Apple software ecosystem. Specifically, these updates mend issues that could allow “maliciously crafted web content” to facilitate cross-site scripting attacks, identified under CVE codes 2024-44308 and 2024-44309.
The Implications of Not Updating
Cybersecurity experts and agencies, including the U.S. Cybersecurity and Infrastructure Agency (CISA), have emphasized the severity of these vulnerabilities. “A cyber threat actor could exploit some of these vulnerabilities to take control of an affected system,” warned a CISA spokesperson. Apple and CISA both recommend that users promptly apply the updates to mitigate any risk of cyber-attacks.
