BIT-HUBBLE-RELAY-2023-30851 Potential HTTP policy bypass when using header rules in Cilium

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. This issue only impacts users who have a HTTP policy that applies to multiple toEndpoints AND have an allow-all rule in place that affects only one of those endpoints. In such cases, a wildcard rule will be...

BIT-CILIUM-OPERATOR-2023-39347 Cilium NetworkPolicy bypass via pod labels

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An attacker with the ability to update pod labels can cause Cilium to apply incorrect network policies. This issue arises due to the fact that on pod update, Cilium incorrectly uses user-provided pod labels...

BIT-CILIUM-OPERATOR-2023-41332 Denial of service via Kubernetes annotations in specific Cilium configurations

Cilium is a networking, observability, and security solution with an eBPF-based dataplane.
