CVE-2026-28870

Sensitive user-data disclosure via GeoServices validation gap

Published Mar 25, 2026 · Updated Mar 25, 2026

Information disclosure in GeoServices before 26.4 allows local users on iOS, iPadOS, macOS, tvOS, visionOS, and watchOS to read user data. Apple identifies insufficient validation in GeoServices but has not disclosed the request path, validation rule, or data classes exposed. Exploitation requires a locally installed low-privilege app and no user interaction; Apple reports no data modification or service interruption.
