Access Control Bypass

Overview Affected versions of this package are vulnerable to Access Control Bypass via the backendRef filters process. An attacker can manipulate the filter context applied to requests by creating an accepted HTTPRoute that shares the same backend Service:port, potentially causing their route's...

CVE-2026-54765

Traefik is an open source HTTP reverse proxy and load balancer. From v3.7.0 prior to v3.7.6, Traefik'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...

CiliumLocalRedirectPolicy addressMatcher allows cross-namespace service traffic hijacking and can break service translation

Impact Users with the ability to create CiliumLocalRedirectPolicies can specify arbitrary ClusterIPs via addressMatcher, which enables hijacking traffic to Services in any namespace, bypassing the namespace-scoping guarantees enforced by serviceMatcher. In addition, deleting such a policy can...
