Apple has just released an update to macOS Sequoia, bringing it to version 15.1.1, build 24B91 (all Macs other than M4) or 24B2091 (M4 Macs only). This brings two important security fixes, to JavaScriptCore and WebKit, both of which Apple believes may already have been exploited. The update should be less than 800 MB to download.
Safari is updated to version 18.1.1 (20619.2.8.11.12). There are also matching updates to Safari available for Sonoma and Ventura, addressing the same vulnerabilities.
Security release notes are here.
