Improper Control of Generation of Code ('Code Injection') Affecting org.webjars.npm:pug-code-gen package, versions [0,]

org.webjars.npm:pug-code-gen is a Default code-generator for pug. It generates HTML via a JavaScript template function.

Affected versions of this package are vulnerable to Improper Control of Generation of Code ('Code Injection') via the name option of the compileClient, compileFileClient, or compileClientWithDependenciesTracked functions. An attacker can execute arbitrary JavaScript code by providing untrusted input.

Note:

These functions are for compiling Pug templates into JavaScript, and there would typically be no reason to allow untrusted callers.

const express = require("express")
const pug = require("pug")
const runtimeWrap = require('pug-runtime/wrap');

const PORT = 3000

const app = express()

app.get("/", (req, res) => {
  const out = runtimeWrap(pug.compileClient('string of pug', req.query))
  res.send(out())
})

app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`)
})
