Weaknesses
Common security weaknesses mapped to this vulnerability.
CWE-305
Authentication Bypass by Primary Weakness
The 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-863
Incorrect Authorization
