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 Real Estate Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.0.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

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 Real Estate Pro WordPress plugin (versions up to 1.0.9) contains a Stored XSS vulnerability in admin settings due to insufficient input sanitization and output escaping. Authenticated attackers with administrator-level permissions can inject malicious scripts that execute when users access affected pages. This only impacts multi-site WordPress installations or sites where unfiltered_html is disabled.

MitigationUpdate to a patched version of the plugin once available; otherwise, ensure unfiltered_html is enabled and restrict administrator access to trusted users only. For multi-site installations, review and harden network settings.

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 WordPress multi-site status
    Check your WordPress configuration by looking for 'MULTISITE' defined as true in wp-config.php, or check the Sites menu in the network admin dashboard.
    Affected if WordPress is configured as a multi-site (network) installation - this condition makes the site vulnerable regardless of other settings.
  2. Check unfiltered_html capability
    As an administrator, go to Users > All Users and edit a user profile. Look for the 'unfiltered_html' capability in the user roles, or use a plugin/network admin query to check if unfiltered_html is disabled for all users.
    Affected if unfiltered_html is disabled for your user roles - this condition makes single-site installations vulnerable.
  3. Verify Real Estate Pro plugin version
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Real Estate Pro' in the list. The version number is displayed below the plugin name.
    Affected if The installed version is 1.0.9 or earlier.
  4. Identify administrator access points
    Review all user accounts with Administrator role in Users > All Users. Check if any administrators were added recently or have unexpected credentials.
    Affected if There are untrusted or compromised administrator accounts that could have injected malicious scripts.

Your environment is affected if you run Real Estate Pro plugin version 1.0.9 or earlier AND either have a multi-site WordPress installation OR have unfiltered_html disabled.
