Descripción

*** Pendiente de traducción *** A race condition in the shared Extreme Platform<br /> ONE IAM Gateway API-key authentication path could, under specific<br /> high-concurrency traffic conditions, intermittently allow requests<br /> authenticated with an Extreme Platform ONE /IAM-issued API key to receive<br /> response data for another tenant. The issue was observed through ExtremeCloud<br /> IQ/XIQ API endpoints and validated against both XIQ/XAPI and Extreme Platform ONE<br /> /Common Services API paths. XIQ-native tokens and standard OAuth/Bearer JWT<br /> authentication were not affected.
