Q4What can hackers do? (Privileges/Data)
π **Privileges**: Full Host System Access. π **Data**: Arbitrary Command Execution. Hackers can run ANY code on your server, not just inside the VM. π€β‘οΈπ»
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: LOW. π« **Auth**: None required (PR:N). π **Access**: Network accessible (AV:N). Simple to exploit without any credentials or user interaction. π

Q7How to self-check? (Features/Scanning)
π **Check**: Scan your `package.json` for `vm2` version. π **Threshold**: If version < 3.10.5, you are vulnerable. π οΈ **Tool**: Use SCA tools to detect this specific library version. π
π§ **Workaround**: If you cannot upgrade immediately, **disable** the `vm2` library or isolate the service running it. 𧱠**Mitigation**: Strict network segmentation and WAF rules. π‘οΈ
