On November 10, according to Apple's security advisory, the iOS and iPadOS 27.2.1 update patched multiple security vulnerabilities, including a Messages flaw that could allow a remote attacker to join an iMessage group chat and receive messages.

Another Messages flaw could allow users newly added to a group chat to read messages sent prior to their addition.
