The iOS 18.4, iPadOS 18.4, and macOS Sequoia 15.4 updates that Apple released on Monday include multiple security fixes, though none of the addressed issues were known to have been exploited.
iOS 18.4 and iPadOS 18.4 fix 60 vulnerabilities, including an issue that could allow sensitive keychain data to be accessible from an iOS backup, a bug that could allow hidden photos to be viewed without authentication, a problem where password autofill filled a password even after a failed authentication.
Apple has a complete list of iOS 18.4 and iPadOS 18.4 fixes in its security support document. There’s a separate security support document for macOS Sequoia 15.4, and the macOS Sequoia 15.4 update addresses over 120 vulnerabilities with everything from AirDrop and the App Store to the Doc and Kernel.
Due to the numerous security vulnerability fixes included in iOS 18.4, iPadOS 18.4, and macOS Sequoia 15.4, iPhone, iPad, and Mac users are advised to update their devices as soon as possible.
