Apple has issued a patch for macOS following the exposure of two critical zero-day vulnerabilities found in the software. The macOS Sequoia 15.1.1 update looks to mitigate a vulnerability in JavaScriptCore that would allow attackers to create malicious web content that could result in arbitrary code execution.

In a security advisory on its website, Apple said it was aware of two vulnerabilities that “may have been actively exploited on Intel-based Mac systems.” The bugs are considered “zero day” vulnerabilities because they were unknown to Apple at the time they were exploited.
