      // 1 advisories

      CVE-2026-56742

      MODERATE
      // impact

      In Cilium clusters using Gateway API, users with permissions to create or update namespaced HTTPRoutes can mirror HTTP traffic to any Service in any namespace, bypassing the ReferenceGrant authorization mechanism.

      Gateway API functionality is disabled by default.

      // patches

      This issue affects:

      • Cilium v1.19 from v1.19.0 to v1.19.4 inclusive
      • Cilium v1.18 from v1.18.0 to v1.18.10 inclusive
      • All versions of Cilium before v1.17.17

      This issue is patched in:

      • Cilium v1.19.5
      • Cilium v1.18.11
      • Cilium v1.17.17
      // workarounds

      There is no workaround to this issue. Users of this feature who are unable to upgrade can mitigate the risk by ensuring that RBAC permissions to create HTTPRoute objects are only granted to cluster admins.

      // acknowledgements

      The Cilium community has worked together with members of Isovalent to prepare these mitigations. Special thanks to @galanko for reporting the issue and @mhofstetter for their work on triaging and remediating this issue.
