Apple Plugs Security Hole That Enabled FBI to Access Deleted Signal Messages on iPhone

Apple has released iOS 26.4.2 and iPadOS 26.4.2 to patch a security flaw affecting notification data on iPhones and iPads.

The bug could leave deleted notifications stored on-device, potentially exposing sensitive messages such as Signal chats.
