CVE-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...

CVE-2023-27595

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...

BIT-CILIUM-OPERATOR-2025-32793 Cilium packets from terminating endpoints may not be encrypted in Wireguard-enabled clusters

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Versions 1.15.0 to 1.15.15, 1.16.0 to 1.16.8, and 1.17.0 to 1.17.2, are vulnerable when using Wireguard transparent encryption in a Cilium cluster, packets that originate from a terminating endpoint can lea...

GHSA-5VXX-C285-PCQ4 In Cilium, packets from terminating endpoints may not be encrypted in Wireguard-enabled clusters

Impact When using Wireguard transparent encryption in a Cilium cluster, packets that originate from a terminating endpoint can leave the source node without encryption due to a race condition in how traffic is processed by Cilium. Patches This issue has been patched in...

CVE-2025-32793

CVE-2025-32793 affects Cilium’s eBPF dataplane when WireGuard transparent encryption is enabled. Versions 1.15.0–1.15.15, 1.16.0–1.16.8, and 1.17.0–1.17.2 are vulnerable to a race condition where packets from a terminating endpoint may leave the source node unencrypted. The issue is fixed in 1.15...
