What it is

Improper Authorization vulnerability in Apache SkyWalking BanyanDB.

The Canopy includes incomplete proof-of-concept role and monitoring-proxy functionality. Under a non-default configuration with a readonly Canopy user and a reachable monitoring target, that user can send non-read requests through the monitoring proxy.

This issue affects Apache SkyWalking BanyanDB: from 0.11.0 before 0.11.1.

Users are recommended to upgrade to version 0.11.1, which fixes the issue.
