Traefik is an HTTP reverse proxy and load balancer. Prior to version 2.6.1, Traefik skips the router transport layer security (TLS) configuration when the host header is a fully qualified domain name (FQDN). For a request, the TLS configuration choice can be different than the router choice, which implies the use of a wrong TLS configuration. When sending a request using FQDN handled by a router configured with a dedicated TLS configuration, the TLS configuration falls back to the default configuration that might not correspond to the configured one. If the CNAME flattening is enabled, the selected TLS configuration is the SNI one and the routing uses the CNAME value, so this can skip the expected TLS configuration. Version 2.6.1 contains a patch for this issue. As a workaround, one may add the FDQN to the host rule. However, there is no workaround if the CNAME flattening is enabled.

### Impact People that configure mTLS between Traefik and clients. For a request, the TLS configuration choice can be different than the router choice, which implies the use of a wrong TLS configuration. - When sending a request using FQDN handled by a router configured with a dedicated TLS configuration, the TLS configuration falls back to the default configuration that might not correspond to the configured one. - If the CNAME flattening is enabled, the selected TLS configuration is the SNI one and the routing uses the CNAME value, so this can skip the expected TLS configuration. ### Patches Traefik v2.6.x: https://github.com/traefik/traefik/releases/tag/v2.6.1 ### Workarounds Add the FDQN to the host rule: Example: ```yml whoami: image: traefik/whoami:v1.7.1 labels: traefik.http.routers.whoami.rule: Host(`whoami.example.com`, `whoami.example.com.`) traefik.http.routers.whoami.tls: true traefik.http.routers.whoami.tls.options: mtls@file ``` There is no workaround if the CNAME flattening is enabled. ### For more information If you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues).
