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 Beaver Builder – WordPress Page Builder for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Caption - On Hover' value associated with images in versions up to, and including, 2.5.5.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with access to the Beaver Builder editor 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 Beaver Builder plugin for WordPress suffers from a stored XSS vulnerability in the image 'Caption - On Hover' field. Authenticated users with Beaver Builder editor access can inject malicious JavaScript via insufficiently sanitized input, which then executes when other users access the affected pages.

MitigationUpdate Beaver Builder to a version newer than 2.5.5.2. Until patched, restrict editor access to only highly trusted users and consider deploying a WAF to help detect XSS exploitation attempts.

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 Beaver Builder is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Beaver Builder Plugin' (Fastlinemedia)
    Affected if Plugin is not installed or not present in the plugins list
  2. Check installed Beaver Builder version
    In WordPress admin, go to Plugins > Installed Plugins, find Beaver Builder, and note the version number displayed under the plugin name
    Affected if Version is 2.5.5.2 or lower (any version up to and including 2.5.5.2)
  3. Identify pages using the Caption - On Hover feature
    In WordPress admin with Beaver Builder active, open the Beaver Builder editor on any page/post. Add an image module and check if the 'Caption - On Hover' field is available in the image settings panel
    Affected if The Caption - On Hover field is present and accessible in the Beaver Builder editor interface
  4. Inspect image caption data for malicious scripts
    Access your WordPress database (via phpMyAdmin or CLI) and query the wp_posts table for any content containing caption fields with script tags or javascript: URIs. Example SQL: SELECT * FROM wp_posts WHERE post_content LIKE '%caption%on%hover%' OR post_content LIKE '%<script%';
    Affected if Any image caption entries contain <script> tags, javascript: event handlers, or other XSS payloads in the database

You are affected if Beaver Builder version 2.5.5.2 or lower is installed AND the Caption - On Hover feature is in use, with potentially malicious script content stored in image captions.
