Traefik v3.7.0 before v3.7.14 contains an improper authentication vulnerability in the Kubernetes Ingress NGINX provider that merges client CAs when auth-tls-secret names collide after dot-to-dash normalization. Attackers holding certificates from another host's CA can access a host requiring its own client CA, while that host's legitimate clients are refused.
