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.

NVD · unedited
Unauthenticated Cross Site Scripting (XSS) in JetEngine <= 3.8.9.1 versions.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Unauthenticated Cross Site Scripting (XSS) vulnerability in JetEngine plugin for WordPress versions 3.8.9.1 and below. The vulnerability can be exploited without requiring authentication, allowing attackers to inject malicious scripts into web pages viewed by other users.

MitigationUpdate JetEngine to the latest version beyond 3.8.9.1 which contains the patched version. Until patched, consider restricting access to the affected endpoints or implementing additional input validation at the web application firewall level.

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 JetEngine plugin is installed
    Navigate to WordPress admin > Plugins and look for JetEngine in the installed plugins list, or check the /wp-content/plugins/jet-engine directory exists on the server
    Affected if JetEngine plugin is present in the WordPress installation
  2. Check installed JetEngine version
    In WordPress admin, go to Plugins > JetEngine > View Details, or inspect the main plugin file header for the Version field, or use WP-CLI: wp plugin get jet-engine --field=version
    Affected if The reported version is 3.8.9.1 or lower
  3. Verify the plugin is active
    Check the Plugins page in WordPress admin to confirm JetEngine status shows as 'Active', or query the database wp_options table for option_name='active_plugins' containing jet-engine
    Affected if JetEngine is activated and running on the site
  4. Confirm unauthenticated access is possible
    Attempt to access the suspected vulnerable endpoint without logging in (e.g., any public-facing JetEngine widget or shortcode), or verify that WordPress general settings do not restrict site access to logged-in users only
    Affected if The site allows unauthenticated visitors and JetEngine components are publicly accessible

The environment is affected if JetEngine plugin is installed, active, and running version 3.8.9.1 or below with unauthenticated access to the site enabled.
