Credential disclosure via missing activity permission check
Published Sep 8, 2026 · Updated Sep 10, 2026
Information disclosure in Google Android 14, 15, 16, 16-qpr2, and 17 allows local users to access device credentials. ConfirmDeviceCredentialActivity.onCreate processes credential-related requests without checking the caller's required permission, allowing unauthorized credential access and modification. A local context is required, but no additional execution privileges or user interaction is needed; the documented security consequence is disclosure.
