  "title": "Algorithmic denial of service in Joi email validation",
  "summary": "Joi email validation with the multiple-address option can consume excessive CPU on long whitespace input, delaying other work in the Node.js process. Applications are exposed when untrusted values reach this rule without a length limit that stops validation before the email check, including public endpoints.",
  "mitigation": "Upgrade npm joi to version 18.3.1 or later. Until a fixed @hapi/joi release is recorded, enforce a maximum input length before the email rule and keep fail-fast validation enabled rather than using abortEarly: false.",
