Apple patches iMessage group-chat flaws and Bluetooth pairing bugs
iOS and iPadOS 27.2.1 also fix Brotli CVE-2026-111497, which CISA added to the Known Exploited Vulnerabilities catalog on October 27.
iMessage group history readable by newly added members
On Apple devices, a person added to an iMessage group may be able to read messages sent before they joined. Triggering it requires being added to that group; no further interaction is described. Apple fixed the issue by removing the vulnerable code in the listed iOS, iPadOS, macOS, visionOS, and watchOS releases. Affected version ranges are not stated.
What to do: Update to iOS/iPadOS 26.7.3 or 27.2.1, macOS Golden Gate 27.2.1, macOS Sequoia 15.8.3, macOS Tahoe 26.7.3, visionOS 27.2.1, or watchOS 27.2.1.
