NVD Description

Note: Versions mentioned in the description apply only to the upstream cilium-1.19 package and not the cilium-1.19 package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

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.
