Apple has published its first “Background Security Improvements” update to fix a security bug in its Safari web browser on iPhones, iPads and Macs.
according to A new safety tip Posted Tuesday, Apple said a security researcher has discovered a bug in WebKit, the browser engine that powers Safari and other apps. If the bug is exploited, it could allow a malicious website to potentially access data from another website in the same browser session.
Apple states that background security fixes are “mild” software updates that contain critical fixes for security vulnerabilities, which the company ships to customers’ devices in between major software updates.
These updates, which begin rolling out to iPhones, iPads, and Macs running the latest version of iOS, iPadOS, and macOS (ver. 26.1 and higher), may include fixes for certain software components, such as Safari, its WebKit engine, and other system libraries that benefit from periodic security updates.
Apple did not provide any reason for why it fixed this specific bug, and an Apple spokesperson did not immediately comment when contacted by TechCrunch.
When we downloaded the new background security update, it only required a quick device restart, not the lengthy reboot usually reserved for software updates with more significant fixes.
Ahead of Tuesday’s first background security fix, Apple published several Security improvements for software testers Testing new update features before they launch.
