  "title": "ruby-rack: Rack is a modular Ruby web server interface",
  "description": "Rack is a modular Ruby web server interface. Prior to version 2.2.18,Rack::QueryParser enforces its params_limit only for parameters separatedby \u0026, while still splitting on both \u0026 and ;. As a result, attackers coulduse ; separators to bypass the parameter count limit and submit moreparameters than intended. Applications or middleware that directly invokeRack::QueryParser with its default configuration (no explicit delimiter)could be exposed to increased CPU and memory consumption. This can beabused as a limited denial-of-service vector. This issue has been patchedin version 2.2.18.",
