CVE-2020-0208

Local privilege escalation via AccountManager permission bypass

Published Jun 11, 2020 · Updated Aug 4, 2024

Elevation of privilege in Android 10 allows local users to bypass AccountManager permissions and modify shared accounts without user interaction. In removeSharedAccountAsUser and related AccountManager functions, missing caller authorization lets an unprivileged application act as a confused deputy against protected account-management operations. Exploitation requires a local application on an affected Android 10 device and can alter shared-account state, enabling escalation into data and capabilities guarded by those permissions.
