v1.15.10->v1.15.13DoS in Cilium agent DNS proxy from crafted DNS responses
BIT-cilium-2025-23028 / BIT-cilium-operator-2025-23028 / BIT-hubble-relay-2025-23028 / CVE-2025-23028 / GHSA-9m5p-c77c-f9j7
More information
Details
Impact
In a Kubernetes cluster where Cilium is configured to proxy DNS traffic, an attacker can crash Cilium agents by sending a crafted DNS response to workloads from outside the cluster.
For traffic that is allowed but without using DNS-based policy, the dataplane will continue to pass traffic as configured at the time of the DoS. For workloads that have DNS-based policy configured, existing connections may continue to operate, and new connections made without relying on DNS resolution may continue to be established, but new connections which rely on DNS resolution may be disrupted. Any configuration changes that affect the impacted agent may not be applied until the agent is able to restart.

Cilium has an information leakage via insecure default Hubble UI CORS header
BIT-cilium-2025-23047 / BIT-cilium-operator-2025-23047 / BIT-hubble-relay-2025-23047 / CVE-2025-23047 / GHSA-h78m-j95m-5356
More information
Details
Impact
For users who deploy Hubble UI using either Cilium CLI or via the Cilium Helm chart, an insecure default
Access-Control-Allow-Originheader value could lead to sensitive data exposure. A user with access to a Hubble UI instance affected by this issue could leak configuration details about the Kubernetes cluster which Hubble UI is monitoring, including node names, IP addresses, and other metadata about workloads and the cluster networking configuration. In order for this vulnerability to be exploited, a victim would have to first visit a malicious page.Patches
This issue was patched in cilium/cilium@a3489f1
This issue affects:
This issue is patched in:
Workarounds
Users who deploy Hubble UI using the Cilium Helm chart directly can remove the CORS headers from the Helm template as shown in the patch.
