## Overview

A missing authorization check in Brocade Fabric OS versions before 10.0.1 REST API interface of affected platform releases allows an authenticated user, regardless of their assigned role or administrative scope, to retrieve complete Monitoring and Alerting Policy Suite (MAPS) violation data across all logical switches. An attacker with low-privilege API access can leverage this endpoint to dump chassis-wide system health metrics, port performance violations, and configuration data without appropriate privileges.
