Threats Tagged 'cve-2025-30163'

### Impact [Node based network policies](https://docs.cilium.io/en/stable/security/policy/language/#node-based) (`fromNodes` and `toNodes`) will incorrectly permit traffic to/from non-node endpoints that share the labels specified in `fromNodes` and `toNodes` sections of network policies. Node based network policy is disabled by default in Cilium. ### Patches This issue was fixed by https://github.com/cilium/cilium/pull/36657. This issue affects: - Cilium v1.16 between v1.16.0 and v1.16.7 inclusive - Cilium v1.17 between v1.17.0 and v1.17.1 inclusive This issue is fixed in: - Cilium v1.16.8 - Cilium v1.17.2 ### Workarounds Users can work around this issue by ensuring that the labels used in `fromNodes` and `toNodes` fields are used exclusively by nodes and not by other endpoints. ### Acknowledgements The Cilium community has worked together with members of Isovalent to prepare these mitigations. Special thanks to @oblazek for reporting and fixing this issue. ### For more information If you think you have found a vulnerability affecting Cilium, we strongly encourage you to report it to our security mailing list at [[email protected]](mailto:[email protected]).
