Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In version 1.13.0, when Cilium is started, there is a short period when Cilium eBPF programs are not attached to the host. During this period, the host does not implement any of Cilium's featureset. This ca...

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. When run in debug mode, Cilium will log the contents of the cilium-secrets namespace. This could include data such as TLS private keys for Ingress and GatewayAPI resources. An attacker with access to debug...

BIT-HUBBLE-UI-BACKEND-2023-30851

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...

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. For Cilium users who have enabled an external kvstore and Wireguard transparent encryption, traffic between pods in the affected cluster is not encrypted. This issue affects Cilium v1.14 before v1.14.7 and...
