Vulnerability from cvelistv5 – Published: 2026-05-11 16:02 – Updated: 2026-05-11 18:18

Title

Meari OpenAPI device status IDOR

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".

Severity

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
