In addInputMethodListener of com.android.server.inputmethod.InputMethodManagerService, there is a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local privilege escalation in Google Android XR stems from a missing permission check in InputMethodManagerService.addInputMethodListener, allowing an app or local context to register input method listeners without the authorization the IME subsystem normally requires. The flaw needs no user interaction and no additional execution privileges, and is addressed in the June 2026 Android XR security bulletin; no public exploit identified at time of analysis.
