Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

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. Verify liveforms plugin is installed
    Navigate to WordPress Admin > Plugins page, or check the wp-content/plugins/ directory for a folder named 'liveforms' or 'w3eden'
    Affected if The liveforms or W3eden Live Forms plugin folder exists in the WordPress installation
  2. Identify the installed version
    In WordPress Admin > Plugins, locate the liveforms plugin and read the version number displayed, or open the main plugin PHP file (e.g., liveforms.php) and look for the 'Version' header comment
    Affected if The version displayed is less than 3.4.0 or no version is shown (indicating an old unversioned release)
  3. Confirm the plugin is active
    In WordPress Admin > Plugins, check the status indicator for liveforms - it should show 'Active' under the plugin name
    Affected if The plugin is active and the version is below 3.4.0, making the XSS flaw potentially exploitable

You are affected if the liveforms/W3eden Live Forms plugin is installed, active, and running at a version lower than 3.4.0, since that is the vulnerable version range for this XSS CVE.
