CVE-2026-65602
Traefik before 3.6.23 IngressRouteTCP ServersTransport Namespace Bypass
Traefik 3.6.0 through 3.6.22 and 3.7.0 through 3.7.6 fail to enforce the crossProviderNamespaces allowlist for IngressRouteTCP service serversTransport references (the allowlist was only enforced for HTTP serversTransport references). A low-privileged Kubernetes user in a namespace not listed in crossProviderNamespaces can set serversTransport: foo@file on an IngressRouteTCP service, causing Traefik to accept the forbidden cross-provider reference and use a file-provider TCPServersTransport — including privileged backend mTLS client certificates, SPIFFE identity, or PROXY-protocol settings. This is fixed in 3.6.23 and 3.7.7.

Traefik CRD IngressRouteTCP ServersTransport Cross-Provider Namespace Bypass
Summary
There is a medium-severity cross-provider reference vulnerability in Traefik's Kubernetes CRD provider. The crossProviderNamespaces allowlist is enforced for HTTP serversTransport references but was not enforced for IngressRouteTCP service serversTransport references. A low-privileged Kubernetes user in a namespace that is not listed in crossProviderNamespaces could set serversTransport: foo@file on an IngressRouteTCP service, causing Traefik to accept the forbidden cross-provider reference and use the file-provider TCPServersTransport — including privileged backend mTLS client certificates, SPIFFE identity, or PROXY-protocol settings. The fix applies the crossProviderNamespaces allowlist to TCP serversTransport references.

<details> <summary>Original Description</summary>
Summary
Traefik's Kubernetes CRD provider enforces crossProviderNamespaces for several
cross-provider references, but IngressRouteTCP service
serversTransport references skip that allowlist. A low-privileged Kubernetes
user in a namespace that is not listed in crossProviderNamespaces can still
set serversTransport: foo@file on an IngressRouteTCP service. Traefik
accepts the forbidden cross-provider reference and later uses the referenced
TCPServersTransport, including privileged backend mTLS client certificates,
SPIFFE identity, or PROXY protocol settings.
Description
crossProviderNamespaces is documented and implemented as an allowlist for
namespaces that may declare cross-provider references from Kubernetes CRD
objects. HTTP serversTransport references enforce that allowlist. TCP
serversTransport references do not.
An attacker with low Kubernetes privileges in namespace default can create an
IngressRouteTCP service with:
serversTransport: foo@file
Even when the provider is configured with:
crossProviderNamespaces:
- operator-only
Traefik still emits a TCP dynamic service whose load balancer points to
foo@file. At runtime, DialerManager.Build() uses the exact referenced
transport name and applies that transport's TLS client certificates and related
backend-connection settings.
Impact
The PoC demonstrates two positive facts:
- A namespace outside
crossProviderNamespacescan cause Traefik to accept and storeLoadBalancer.ServersTransport = "foo@file"from anIngressRouteTCPservice. - A qualified
foo@fileTCPServersTransportwith a client certificate is actually consumed by the TCP dialer and presented to an mTLS backend.
This proves a backend identity relay primitive: a lower-privileged CRD author can make Traefik connect to a backend using an operator-defined cross-provider transport identity that the namespace should not be allowed to reference.
