  "title": "Node.js 20: Improper Access Control",
  "description": "A vulnerability in Node.js version 20 allows for bypassing restrictions set by the --experimental-permission flag using the built-in inspector module (node:inspector).\n\nBy exploiting the Worker class\u0027s ability to create an \u0022internal worker\u0022 with the kIsInternal Symbol, attackers can modify the isInternal value when an inspector is attached within the Worker constructor before initializing a new WorkerImpl. This vulnerability exclusively affects Node.js users employing the permission model mechanism.\n\nPlease note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.",
