CVE-2023-41333

Cilium is vulnerable: an attacker who can create/modify CiliumNetworkPolicy objects in a namespace can bypass namespace restrictions and affect traffic across the entire cluster by crafting an endpointSelector that uses the DoesNotExist operator on the reserved:init label. The issue requires API ...
