CVE-2022-40703

Authentication bypass via intent manipulation

Published Oct 26, 2022 · Updated Apr 16, 2025

Authentication bypass in AliveCor Kardia App 5.17.1-754993421 and prior on Android allows unauthenticated attackers to alter information via physical access. Android Intent Manipulation changes how the app handles inter-app intents, allowing authentication checks to be bypassed and protected records to be viewed or altered. Physical possession of the device is required; the documented impact is unauthorized disclosure and modification of app information, not service interruption.
