Apple released iOS 27.2.1 on Nov. 9 to address nine security issues, a day before cryptocurrency exchange Binance warned that another iOS flaw could expose locally stored wallet credentials.
Apple said one of the patched weaknesses might have let a remote attacker enter an iMessage group and receive messages intended for its members. Another could have given a newly added participant access to messages sent before they joined. The update also addresses a Bluetooth pairing flaw that required no action from the user and an app authorization issue that could have exposed sensitive data.
Binance said on Nov. 10 that a flaw it calls worse_query could allow a malicious app to read files held by other apps on devices running iOS 26.7.1, 27.0.1 or 27.2. The exchange warned that passwords and locally stored cryptocurrency wallet credentials could be exposed. The researcher behind the project describes the flaw as an escape from the app sandbox, which is meant to restrict an app’s access to other apps’ files.
Apple’s iOS 27.2.1 advisory does not name worse_query, and Apple has not confirmed whether the update fixes it. Binance advised users to remove apps installed from untrusted sources and update their operating system and apps. EconoTimes has previously covered warnings about iOS flaws and locally stored wallet data.
The security patch followed iOS 27.2, which changed six Apple apps. Messages can suggest actions based on details in a conversation, such as creating a calendar event, and users can choose which suggestions appear. Apple TV gained separate household profiles, Podcasts divided its Home queue into new and unfinished episodes, and Games added context to friend suggestions and displayed friends’ recent games.
9to5Mac reported that iOS 27.2 extended FaceTime’s simultaneous front and rear camera view to group calls on compatible iPhones. The outlet also reported that the Home app added two options for compatible smart locks: locking a door after it closes and alerting users when it remains open beyond a chosen period.
Apple also released iOS 26.7.3 and iOS 18.7.12 on Nov. 9. Users can check for an available update under Settings > General > Software Update.
