Apple has issued critical security updates for its devices, addressing two zero-day vulnerabilities that have been actively exploited in the wild. The flaws, identified as CVE-2024-44308 and CVE-2024-44309, affect the JavaScriptCore and WebKit components in Apple’s operating systems. CVE-2024-44308, with a CVSS score of 8.8, allows for arbitrary code execution when malicious web content is processed, while CVE-2024-44309 (CVSS score: 6.1) could enable cross-site scripting (XSS) attacks through a cookie management flaw. These vulnerabilities pose significant risks to users, particularly those using Intel-based Mac systems, where the flaws have been actively exploited.
The vulnerabilities were discovered by Clément Lecigne and Benoît Sevens from Google’s Threat Analysis Group. Their research suggests that these exploits have been used in highly-targeted attacks, likely attributed to government-backed or mercenary spyware groups. The flaws allow attackers to execute malicious code or inject harmful scripts, potentially compromising user data and privacy. Apple has responded by improving checks and state management within the affected components to mitigate these risks.
Affected devices include those running iOS 18.1.1, iPadOS 18.1.1, macOS Sequoia 15.1.1, visionOS 2.1.1, and Safari 18.1.1. The updates are available for a range of devices, including iPhones (XS and later), iPads (6th generation and later), and Macs running macOS Sequoia or earlier versions like macOS Ventura and Sonoma. Apple recommends that users update their devices as soon as possible to protect against the ongoing threat. The company has been proactive in addressing zero-day vulnerabilities this year, having patched a total of four such flaws, underscoring its commitment to security.
In addition to issuing these patches, Apple continues to emphasize the importance of keeping devices up to date with the latest security patches. Given the severity of these flaws and the likelihood of continued exploitation, users are strongly advised to install the latest software updates immediately. Regular updates are essential to maintaining the security and integrity of devices, especially in the face of sophisticated, targeted cyberattacks. Apple’s swift response highlights the company’s ongoing efforts to protect its vast user base from emerging security threats.
