security/vuxml: Register sysutils/node_exporter vulnerability

CVE-2022-46146 Note that in https://cgit.freebsd.org/ports/commit/?id=8b5d2b9a9ec7985158a814e2cdf9022d785b9090 three CVEs are mentioned: CVE-2022-27191 CVE-2022-27664 CVE-2022-46146 However, according to: prometheus/node_exporter#2488 node_exported is not really affected by those Go vulnerabilities.

+	  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.
