Apple patches iOS 26.4.2 to close flaw exposing deleted push notifications

Apple released iOS 26.4.2 to fix a security flaw in its notification database that could let law enforcement access data from deleted push notifications on iPhone and iPad; the update adds improved data redaction and covers devices from iPhone 11 onward and several iPad models; the issue surfaced after reports that the FBI used a tool to read locally stored Signal notifications even after deletion, prompting Signal to welcome the patch and advise users to limit content in notifications; privacy advocates note vulnerabilities in both cloud routing and local storage, but Apple’s fix aims to make deleted notifications inaccessible.
