  "title": "Algorithmic denial of service in joi email validation",
  "summary": "Joi email validation using `string().email({ multiple: true })` is affected when it accepts attacker-controlled input without an effective length limit. A crafted long value can consume excessive CPU time and delay other Node.js event-loop work. The issue requires use of the multiple-email validation option.",
  "mitigation": "Upgrade joi to version 18.3.1. Until upgrades are complete, enforce request-size limits before Joi validation and avoid applying the affected multiple-email rule to untrusted unbounded input.",
