github.com/traefik/traefik: Traefik: Information disclosure via crossProviderNamespaces bypass in Kubernetes Ingress provider
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon NVD. Plus basse selon Red Hat (élevée).
Description
Traefik versions from v3.7.1 fail to enforce crossProviderNamespaces restrictions on the traefik.ingress.kubernetes.io/service.middlewares Service annotation in the Kubernetes Ingress provider. A namespace-limited tenant excluded from the allowlist can attach an operator-owned middleware to its Service, and if that middleware injects backend credentials, recover them at a controlled backend.
