Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm plugin is installed
    Access WordPress admin dashboard, navigate to Plugins section, or check /wp-content/plugins/ directory for wp-live-chat-support folder
    Affected if wp-live-chat-support or 3cx Live Chat plugin is present in the WordPress installation
  2. Identify installed version
    In WordPress Plugins admin page, locate wp-live-chat-support and view the version number displayed beneath the plugin name, or read version.php in the plugin directory
    Affected if Version displayed is lower than 7.1.03
  3. Verify chat feature is active
    Check WordPress plugins page to confirm wp-live-chat-support is activated, or attempt to access the chat widget on the live site (typically loads via shortcode or widget)
    Affected if Plugin is activated and chat functionality is accessible to visitors
  4. Confirm vulnerability condition
    Since this is an unauthenticated XSS in chat interfaces, any site where the live chat is enabled and exposed to users is potentially affected
    Affected if Live chat feature is enabled and accessible without authentication to website visitors

The environment is affected if wp-live-chat-support or 3cx Live Chat plugin is installed with a version lower than 7.1.03 and the chat feature is active and accessible to users.
