Summary
In Meari client applications embedding "com.meari.sdk" (including CloudEdge 5.5.0 build 220, Arenti 1.8.1 build 220, and related white-label <= 1.8.x), the integrated call path to openapi-euce.mearicloud.com can be abused to retrieve WAN IP data for arbitrary devices. The root cause is a server-side authorization failure in "GET /openapi/device/status".
