Apple has released iOS 27.1. Users on iPhone and iPad should update once the build is available for their device. The list of fixed vulnerabilities for 27.1 could not be confirmed from the material available, so treat the security content as unverified.
DETAILS
- The release of iOS 27.1 is the triggering event. The material contains no Apple advisory text or CVE identifiers specific to 27.1.
- SecurityWeek reported that Apple’s iOS 27 and macOS Golden Gate 27 releases fixed about 200 vulnerabilities. The excerpt is truncated and does not confirm that any of these fixes ship in 27.1.
- A separate SecurityWeek report describes 87 vulnerabilities fixed in iOS and 155 in macOS Tahoe. The excerpt gives no release date or version, so it cannot be tied to 27.1.
- Recent Apple releases have repeatedly included WebKit fixes, as reported by SecurityWeek and news4hackers. Safari 27 advisory APPLE-SA-09-14-2026-9 was posted September 22, 2026. Neither source confirms its contents for 27.1.
- MacRumors reported that iOS 26.5.2 fixed more than 25 vulnerabilities. 9to5Mac reported that Apple is accelerating security updates in response to AI-assisted hacking risks.
