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 plugin installation
    Navigate to WordPress admin dashboard, go to Plugins > Installed Plugins, and locate 'Team Heateor Fancy Comments' or 'Heateor Fancy Comments' in the list of installed plugins.
    Affected if The plugin appears in the installed plugins list.
  2. Check installed plugin version
    In the Plugins list, click on the plugin name or view the plugin details to find the version number displayed under the plugin name. Compare this version to the affected range: versions 1.2.10 and below are vulnerable, version 1.2.11 and above are patched.
    Affected if The installed version is 1.2.10 or lower.
  3. Confirm plugin is active
    In the WordPress Plugins admin page, verify whether the Heateor Fancy Comments plugin has an 'Activate' or 'Deactivate' status. An activated plugin shows 'Deactivate' link.
    Affected if The plugin is currently active (showing 'Deactivate' option).
  4. Identify elevated permission users
    Go to WordPress admin dashboard > Users section and review user roles. Look for any accounts with Contributor, Author, Editor, or Administrator roles, as these permissions allow access to the plugin functionality that can trigger the XSS.
    Affected if At least one user account with Contributor-level permissions or higher exists on the site.
