Medium (6.3). EPSS 0.2% chance of exploitation in the next 30 days.
A race condition in the shared Extreme Platform
ONE IAM Gateway API-key authentication path could, under specific
high-concurrency traffic conditions, intermittently allow requests
authenticated with an Extreme Platform ONE /IAM-issued API key to receive
response data for another tenant. The issue was observed through ExtremeCloud
IQ/XIQ API endpoints and validated against both XIQ/XAPI and Extreme Platform ONE
/Common Services API paths. XIQ-native tokens and standard OAuth/Bearer JWT
authentication were not affected.
