CVE-2021-1848

Sensitive information exposure via app-switcher UI handling

Published Sep 8, 2021 · Updated Aug 3, 2024

Information disclosure in Wallet in Apple iOS and iPadOS before 14.5 allows local users to view sensitive data in the app switcher. Wallet does not reliably conceal sensitive interface content when the app switcher presents the application; Apple has not disclosed the specific UI-handling error. Access requires local use of an affected device, and the documented consequence is limited to viewing information exposed in the app switcher.
