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
The PQ Addons – Creative Elementor Widgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via widget attributes in all versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping on the html_tag parameter in the PQ Section Title widget. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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 · high confidence

The PQ Addons WordPress plugin's PQ Section Title widget fails to sanitize the html_tag parameter during input and escape it during output, allowing authenticated users with contributor-level permissions to inject persistent malicious JavaScript that executes whenever pages containing the widget are accessed.

MitigationUpdate the plugin to a version that properly sanitizes the html_tag parameter using WordPress sanitization functions (such as sanitize_html_class or similar) and implements output escaping (such as esc_attr) when rendering the widget.

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. Check if PQ Addons plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'PQ Addons' or check the plugin directory wp-content/plugins for a pq-addons folder
    Affected if PQ Addons plugin is not installed or not present on the system
  2. Identify the installed version of PQ Addons plugin
    In WordPress admin, view the plugin details from Plugins > Installed Plugins to see the version number, or read the main plugin file header in wp-content/plugins/pq-addons/
    Affected if The installed version has not received the fix for html_tag sanitization and escaping
  3. Determine if PQ Section Title widget is in use
    Check WordPress widget areas under Appearance > Widgets for the 'PQ Section Title' widget, or query the wp_postmeta table for meta_key containing 'widget_pq_section_title' or 'pq_section_title'
    Affected if The PQ Section Title widget is added to any sidebar, footer, or page builder area
  4. Verify contributor-level user accounts exist
    Review user roles under Users > All Users and note any accounts with 'Contributor' role
    Affected if At least one user account has contributor-level permissions and could potentially exploit this vulnerability if the widget is in use

The environment is affected if the PQ Addons plugin is installed with a vulnerable version and the PQ Section Title widget is actively used on the site, allowing authenticated contributors to inject JavaScript via the unsanitized html_tag parameter.
