Description
vm2 is a Node.js sandbox that prior to version 3.11.4 allowed sandboxed code to bypass network restrictions by accessing internal underscored HTTP modules. Although public network modules could be excluded, internal modules like _http_client and _http_server were not blocked, enabling outbound HTTP requests and listening sockets. This vulnerability is fixed in version 3.11.4.
