  "title": "Regular-expression denial of service in Ring nested-params",
  "summary": "Ring versions before 1.15.5 can consume excessive CPU while parsing request parameter names through the nested-params middleware. A remote attacker may cause denial of service with specially formed query-string or request-body parameter names when an application uses `wrap-nested-params`, including through Ring-Defaults.",
  "mitigation": "Upgrade the Ring package to version 1.15.5 or later. If an immediate upgrade is not possible, disable or avoid `wrap-nested-params` where application requirements permit.",
