+description: |
+    The Prometheus client_golang HTTP server is vulnerable to a denial of
+    service attack when handling requests with non-standard HTTP methods.
+
+    In order to be affected, an instrumented software must use any of
+    the promhttp.InstrumentHandler* middleware except `RequestsInFlight`;
+    not filter any specific methods (e.g GET) before middleware;
+    pass a metric with a "method" label name to a middleware; and not
+    have any firewall/LB/proxy that filters away requests with unknown
+    "method".
