iOS 26.4.2 fixes bug that allowed deleted notifications to be retrieved

iOS 26.4.2 is available now as the latest iPhone update, and it includes a key security fix that ensures deleted notifications can’t be retrieved or restored later.

Important security fix available now in iOS 26.4.2

Apple’s latest software update is iOS 26.4.2, which includes new bug fixes and security updates for iPhone.

While some of the changes are unspecified, Apple has chosen to highlight one important fix.

From its webpage covering iOS 26.4.2 security updates:

Notification Services

Impact: Notifications marked for deletion could be unexpectedly retained on the device

Description: A logging issue was addressed with improved data redaction.

Apple told 9to5Mac that it became aware of reports that some push notifications from apps were being retained on-device when they should have been deleted.

This led the company to identify the bug in question and implement the fix in iOS 26.4.2.

Apple says the new update not only fixes the bug, but also retroactively purges any notification copies that had been unexpectedly stored on-device.

9to5Mac’s Take

Apple didn’t say this explicitly, but iOS 26.4.2’s fix is likely in response to the recent report involving the FBI. The FBI successfully retrieved Signal notifications from a defendant’s iPhone even after the Signal app had been deleted.

Clearly, Apple’s intent is that when an app is deleted, all prior notifications are removed as well. And now that should happen every time, as expected.

In addition to iOS 26.4.2, today’s notification fix is available in iPadOS 26.4.2, iOS 18.7.8, and iPadOS 18.7.8.
