HashiCorp Consul and Consul Enterprise up to 1.9.16, 1.10.9, and 1.11.4 may allow server side request forgery when the Consul client agent follows redirects returned by HTTP health check endpoints. Fixed in 1.9.17, 1.10.10, and 1.11.5.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
