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 Elementor Addons by Livemesh plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Marquee Text Widget, Testimonials Widget, and Testimonial Slider widgets in all versions up to, and including, 8.4.1 due to insufficient input sanitization and output escaping on user supplied attributes. 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 Elementor Addons by Livemesh plugin for WordPress versions up to 8.4.1 contains a stored Cross-Site Scripting (XSS) vulnerability in the Marquee Text Widget, Testimonials Widget, and Testimonial Slider widgets. The vulnerability stems from insufficient input sanitization and output escaping on user-supplied attributes, allowing authenticated attackers with contributor-level permissions or higher to inject malicious JavaScript that executes whenever users access affected pages.

MitigationUpdate the Elementor Addons by Livemesh plugin to version 8.4.2 or later to remediate the stored XSS vulnerability. Review existing pages using the affected widgets for any injected malicious scripts.

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 version
    Navigate to WordPress Admin > Plugins > Installed Plugins > Elementor Addons by Livemesh and check the Version field
    Affected if The version displayed is 8.3.7 or lower
  2. Identify affected widgets in use
    Go to any WordPress page/post editor using Elementor and look for the Livemesh widget panel. Check if Marquee Text, Testimonials, or Testimonial Slider widgets have been added to any published pages
    Affected if Any of these three widgets (Marquee Text, Testimonials, Testimonial Slider) are present on live pages
  3. Inspect widget attributes for malicious scripts
    Edit each affected page containing the vulnerable widgets. For each widget, open its settings panel and examine fields such as author name, quote text, client name, or any text input fields for suspicious <script> tags, event handlers (onload, onerror, onclick), or javascript: URLs
    Affected if Any text field contains raw HTML/JavaScript such as <script>, javascript:, onerror=, or onload= attributes that were not intentionally added by an administrator
  4. Review page source for injected scripts
    View the source HTML of pages containing the affected widgets. Search for any <script> tags or event handler attributes that originate from widget text fields rather than theme/plugin code
    Affected if Unexpected script tags or event handlers appear in the rendered HTML tied to Livemesh widget content

You are affected if the Livemesh Elementor Addons plugin version is 8.3.7 or lower AND any published pages use the Marquee Text, Testimonials, or Testimonial Slider widgets with untrusted user input in their text fields.
