Application-state misrepresentation via privileged network
Published Sep 8, 2021 · Updated Aug 3, 2024
A logic issue in Mail in Apple macOS Big Sur before 11.4 allows attackers in a privileged network position to misrepresent application state. Apple identifies the affected locus only as Mail and describes improved state management, without publishing the faulty operation or a reproducible input sequence. Exploitation requires control of a privileged network position; the documented consequence is altered application-state representation rather than disclosed code execution or data theft.
