You might want to snag these updates.
Apple on Tuesday released its iOS 18.1.1, iPadOS 18.1.1, and macOS Sequoia 15.1.1 updates. The patches address JavaScriptCore and WebKit vulnerabilities that Apple says have been actively exploited on some devices.
With the JavaScriptCore vulnerability, processing maliciously crafted web content could lead to arbitrary code execution. The WebKit vulnerability had the same issue with maliciously crafted web content, and it could lead to a cross-site scripting attack.
The company has stated that it is aware of reports that the two issues could have been actively exploited on Intel-based Macs. While the vulnerabilities are only known to have impacted older Macs, other devices are vulnerable to attack because they have the same security flaws.
As always, you can locate, download, and install the updates by navigating to Settings > General > Software Update on your iPhone or iPad or System Settings > Software Update on your Mac.
