Safari 26.2 Security Update

What Safari 26.2 Fixes

Safari 26.2, released December 12, 2025, fixes 13 vulnerabilities in 4 parts of the system, according to Apple's security advisory.

Apple says 2 of these flaws — CVE-2025-43529, CVE-2025-14174 — may already have been exploited. That makes Safari 26.2 an update to install now rather than at the weekend.

It has since been superseded: the newest security release for Safari is Safari 27.2, from October 26, 2026, which includes these fixes.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

Exploited Before the Fix

Apple flags a fix as possibly exploited when it has a credible report that the flaw was used against real people before the patch. These are the reason to update today.

Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 26. CVE-2025-14174 was also issued in response to this report.

  A use-after-free issue was addressed with improved memory management.

How to Install Safari 26.2

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 26.2 there is nothing to do.
