Mitigation checklist
- To mitigate this issue, avoid enabling the experimental Node.js Permission Model by not using the `--experimental-permission` flag. Additionally, ensure that untrusted Node.js workloads are executed within robust operating system isolation primitives, such as Linux containers or cgroups, to limit potential impact.
