CyberRota Analysis
AI-GeneratedCilium clusters prior to specified versions are vulnerable to a flaw that allows users with permissions to create or update namespaced HTTPRoutes to redirect HTTP traffic to any Service across namespaces, circumventing the ReferenceGrant authorization controls. This could lead to unauthorized access and data exposure within the network. Organizations utilizing Cilium, especially those with Gateway API enabled, should prioritize upgrading to the patched versions to mitigate this risk.

Original NVD Description
Cilium is a networking, observability, and security solution. Prior to 1.17.17, 1.18.11, and 1.19.5, Cilium clusters using Gateway API allow users with permissions to create or update namespaced HTTPRoutes to mirror HTTP traffic to any Service in any namespace, bypassing the ReferenceGrant authorization mechanism. Gateway API functionality is disabled by default. This issue is fixed in versions 1.17.17, 1.18.11, and 1.19.5.
