      HIGHCVE-2026-50194
      // summary

      When Steeltoe management endpoints are configured to listen on an alternate port (Management:Endpoints:Port is configured), the middleware responsible for restricting access to the endpoints uses the Host HTTP header rather than the actual network socket port.

      // impact

      An unauthenticated remote attacker can reach every actuator endpoint using a specially crafted HTTP request.

      // affected configuration
      • The application's public port is accessible over from the network.
      • Management:Endpoints:Port is configured to a value different from the application's main listener port.
      • The request scheme matches Management:Endpoints:SslEnabled. For example, http when SslEnabled is false (the default), or https when SslEnabled is true.
      // mitigations

      If an immediate upgrade to a patched version is not possible:

      • Add explicit ASP.NET Core authorization (RequireAuthorization) to all sensitive actuator endpoints as a defense-in-depth measure independent of port isolation.
      • Configure the reverse proxy or load balancer to enforce the Host header value and prevent clients from setting an arbitrary port.
