+	  Prometheus and its exporters can be secured by a web.yml file that
+	  specifies usernames and hashed passwords for basic authentication.
+	  Passwords are hashed with bcrypt, which means that even if you have
+	  access to the hash, it is very hard to find the original password
+	  back. Passwords are hashed with bcrypt, which means that even if you
+	  have access to the hash, it is very hard to find the original
+	  password back. However, a flaw in the way this mechanism was
+	  implemented in the exporter toolkit makes it possible with people
+	  who know the hashed password to authenticate against Prometheus.
+	  A request can be forged by an attacker to poison the internal cache
+	  used to cache the computation of hashes and make subsequent requests
+	  successful. This cache is used in both happy and unhappy scenarios
+	  in order to limit side channel attacks that could tell an attacker
+	    if a user is present in the file or not.
