From v3.7.0 prior to v3.7.6, Traefik&#8217;s Kubernetes Gateway API provider may resolve two accepted HTTPRoutes that target the same backend Service:port but configure different backendRef filters to the same child service and apply only one route&#8217;s filter set to all requests reaching that backend. In Gateway deployments where backendRef filters set security-sensitive headers, such as tenant identity, authorization context, or values the backend trusts, an attacker who can create an accepted HTTPRoute sharing the same backend Service:port may cause their route&#8217;s filter context to be applied to another route&#8217;s requests, potentially crossing namespace boundaries when a ReferenceGrant permits cross-namespace targeting.
