Apple has released iOS 18.4 and iPadOS 18.4, which include significant security enhancements alongside other improvements. Here’s what you need to know about the update:
Major Security Fixes
Protection of Sensitive User Data

- WebKit Patches: Addressed six vulnerabilities, including malicious content causing crashes and preventing cross-site scripting attacks through improved memory handling.
Additional Security Enhancements
- AirDrop and Journal App: Resolved security issues in these apps.
- Operating System Components: Fixed vulnerabilities in CoreAudio, CoreMedia, libnetcore, and more.
