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. Locate the plugin installation directory
    Access your WordPress site via FTP or file manager and navigate to /wp-content/plugins/ directory. Look for either 'wp-live-chat-support' or '3cx-live-chat' folder.
    Affected if Either folder exists on the server
  2. Read the plugin version from main file
    Open the main plugin PHP file (typically index.php or the plugin's primary PHP file) in the plugin folder. Look for a version comment or define statement at the top of the file.
    Affected if The version displayed is lower than 6.2.02 (for example 6.2.00, 6.1.x, 6.0.x, etc.)
  3. Verify the plugin is active
    Log into WordPress admin panel and go to Plugins > Installed Plugins. Check if wp-live-chat-support or 3cx Live Chat shows as 'Active'.
    Affected if Plugin is installed AND active AND version is below 6.2.02
  4. Check WordPress plugins database table
    If you have database access, query: SELECT * FROM wp_options WHERE option_name LIKE '%active_plugins%' or directly check the plugin files in /wp-content/plugins/
    Affected if The plugin appears in the active plugins list and version is below 6.2.02

Your environment is affected if the wp-live-chat-support or 3cx Live Chat plugin is installed, active, and the installed version is lower than 6.2.02.
