CVE-2023-30587: Inspector protocol bypass the experimental permission model
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).
Other sources
Node.js could allow a remote attacker to bypass security restrictions. By exploiting the Worker class's ability to create an "internal worker" with the kIsInternal Symbol, an attacker could exploit this vulnerability to modify the isInternal value when an inspector is attached within the Worker constructor before initializing a new WorkerImpl.
