Common Weakness Enumeration
- CWE-305 - Authentication Bypass by Primary WeaknessThe authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.
- CWE-287 - Improper AuthenticationWhen an actor claims to have a given identity, the software does not prove or insufficiently proves that the claim is correct.
