Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.6, lib/bridge.js and lib/setup-sandbox.js fail
 to block stacked indirection through Function.prototype.call around dangerous host prototype getter and
 setter mutators, allowing sandbox code to sever a host intrinsic's prototype chain and reach
