Overview
- Apple’s official account urged iPhone users to update iOS to reduce exposure to web-based attacks and to turn on automatic updates, avoid unknown links, and install apps only from the App Store.
- Apple said devices on current releases from iOS 15 through iOS 26 have protection against the reported browser exploits, and users on iOS 13 or 14 need to upgrade to iOS 15 to get those fixes.
- The company is delivering iOS 18.7.7 more broadly through automatic rollout, with older iOS 18 devices receiving extra prompts to install critical security updates.
- Apple stopped signing iOS 26.4 after releasing iOS 26.4.1, which fixed iCloud sync errors and an enterprise lost‑device protection issue.
- Apple Stores, authorized resellers, and authorized service providers are offering software version checks and hands-on help with updates.
