  name: Popup-Maker < 1.8.12 - Broken Authentication
  author: DhiyaneshDK
  severity: critical
  description: |
    An issue was discovered in the Popup Maker plugin before 1.8.13 for WordPress.

  impact: |
    Unauthenticated attackers can gain administrative access to the WordPress site.
  remediation: |
    Update Popup-Maker plugin to version 1.8.12 or later.
