Safari 26 Security Update

What Safari 26 Fixes

Safari 26, released September 15, 2025, fixes 9 vulnerabilities in 3 parts of the system, according to Apple's security advisory.

Apple does not say that any of them were exploited before the fix. That makes Safari 26 a routine security update: worth installing soon, not an emergency.

It has since been superseded: the newest security release for Safari is Safari 27.2, from October 26, 2026, which includes these fixes.

Grouped by us from the impact Apple gives for each fix; the impact lines below are Apple's own.

Which Devices Get Safari 26

How to Install Safari 26

Safari updates arrive through Software Update on the Mac. On a current macOS they are part of the macOS update; on older versions they are offered separately.

Security fixes are cumulative: any later release for the same version includes these as well, so if you are already past Safari 26 there is nothing to do.
