Weaknesses
CWE · root cause- CWE-302Authentication Bypass by Assumed-Immutable DataThe authentication scheme or implementation uses key data elements that are assumed to be immutable, but can be controlled or modified by the attacker.
- CWE-636Not Failing Securely ('Failing Open')When the product encounters an error condition or failure, its design requires it to fall back to a state that is less secure than other options that are available, such as selecting the weakest encryption algorithm or using the most permissive access control restrictions.
- CWE-863Incorrect AuthorizationThe product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
