Kerentanan Authorization Bypass Through User-Controlled Key pada traefik. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

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.
