Insecure randomness High

This uses a cryptographically insecure random number generated at
Math.random()
in a security context.

Copilot Autofix

AI 4 months ago

To fix the issue, replace the use of Math.random() with a cryptographically secure random number generator. In Node.js, the crypto module provides a secure method for generating random bytes. Specifically, crypto.randomBytes can be used to generate a secure random password.

The fix involves:

  1. Importing the crypto module.
  2. Replacing the insecure Math.random() logic with crypto.randomBytes to generate a secure random password.
  3. Ensuring the generated password is converted to a suitable format (e.g., alphanumeric string) without introducing bias.

The changes will be made in the findOneOrCreate method, specifically on line 65.
