  author: s4e-io
  severity: critical
  description: |
    The Shield Security Smart Bot Blocking & Intrusion Prevention Security plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 18.5.9 via the render_action_template parameter. This makes it possible for unauthenticated attacker to include and execute PHP files on the server, allowing the execution of any PHP code in those files.
  impact: |
    Unauthenticated attackers can exploit local file inclusion via render_action_template to execute arbitrary PHP code, potentially compromising the entire WordPress installation.
  remediation: |
    Update Shield Security plugin to version 18.5.10 or later.
