  "summary": "estree-util-value-to-estree allows prototype pollution in generated ESTree",
  "details": "### Impact\nWhen generating an ESTree from a value with a property named `__proto__`, `valueToEstree` would generate an object that specifies a prototype instead.\n\nExample:\n\n```js\nimport { generate } from 'astring'\nimport { valueToEstree } from 'estree-util-value-to-estree'\n\nconst estree = valueToEstree({\n  ['__proto__']: {}\n})\nconst code = generate(estree)\nconsole.log(code)\n```\n\nOutput:\n\n```js\n{\n  \"__proto__\": {}\n}\n```\n\n### Patches\nThis was fixed in version [3.3.3](https://github.com/remcohaszing/estree-util-value-to-estree/releases/tag/v3.3.3).\n\n### Workarounds\nIf you control the input, don’t specify a property named `__proto__`. If you don’t control the output, strip any properties named `__proto__` before passing it to `valueToEstree`.",
