  author: pikpikcu
  severity: medium
  description: Harbor 1.7.0 through 1.8.2 is susceptible to privilege escalation via core/api/user.go, which allows allows non-admin users to create admin accounts via the POST /api/users API when Harbor is setup with DB as an authentication backend and allows user to do self-registration.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to escalate their privileges and gain unauthorized access to sensitive information.
  remediation: Upgrade to v1.7.6 v1.8.3. v.1.9.0 or higher. A potential workaround without applying the fix is to configure Harbor to use a non-DB authentication backend such as LDAP.
