An improper authorization flaw in Apple iOS/iPadOS and macOS Tahoe allows a locally installed application to reach sensitive user data that the platform's authorization state checks should have blocked. Apple addressed the flaw through improved state management, shipping fixes in iOS 26.6, iPadOS 26.6, and macOS Tahoe 26.6 for all versions prior to those releases. The issue is local-only (CVSS:3.1/AV:L/AC:L/PR:L/UI:N, 5.5) with confidentiality impact only; EPSS is 0.15% (5th percentile), CISA SSVC rates exploitation as 'none' and technical impact as 'partial', and no public exploit code was identified at time of analysis.
