AI Powered Q&A
Can you explain this vulnerability to me?
The vulnerability exists in vm2, an open source virtual machine and sandbox for Node.js. Prior to version 3.11.0, the SuppressedError feature allows attackers to escape the sandbox environment and execute arbitrary code outside of the intended restrictions.
How can this vulnerability impact me? :
This vulnerability can have a severe impact as it allows attackers to break out of the sandbox and run arbitrary code on the host system. This can lead to complete compromise of the affected system, including unauthorized access, data theft, data corruption, and disruption of services.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, you should upgrade vm2 to version 3.11.0 or later, where the issue allowing sandbox escape via SuppressedError has been patched.
