Medium (5.3). EPSS 0.2% chance of exploitation in the next 30 days. Fixed in github.com/kgateway-dev/kgateway/v2 2.0.5, 2.1.0.
kgateway is a Cloud-Native API and AI Gateway. Versions 2.0.4 and below and 2.1.0-agw-cel-rbac through 2.1.0-rc.2 lack authentication, allowing any client with unrestricted network access to the xDS port to retrieve potentially sensitive configuration data including certificate data, backend service information, routing rules, and cluster metadata. This issue is solved in versions 2.0.5 and 2.1.0.
