Apple's recent update, iOS 26.4.2, addresses a significant security flaw in its notification database that allowed law enforcement agencies, including the FBI, to access deleted push notifications on iPhones and iPads. This flaw undermined Apple's commitment to user privacy, especially since the company has required a court order to share notification data since 2023. The update introduces 'improved data redaction,' ensuring that notifications marked for deletion are not retained on devices. The update is now available for devices including the iPhone 11 and later, as well as several iPad models. The issue was initially reported by 404 Media, revealing that the FBI used a tool to access Signal notification data even after deletion. Signal's CEO, Meredith Whitaker, acknowledged the problem and urged Apple to rectify it, emphasizing that deleted notifications should not remain in any operating system's notification database. The Electronic Frontier Foundation (EFF) notes that the privacy of notifications is compromised both in the cloud and on local devices, making this update a crucial step in enhancing user privacy.
