The underlying weakness: Authentication Bypass by Assumed-Immutable Data

The authentication scheme or implementation uses key data elements that are assumed to be immutable, but can be controlled or modified by the attacker.

How developers prevent this class of flaw

  • Implement proper protection for immutable data (e.g. environment variable, hidden form fields, etc.)
