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 Essential Real Estate plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ere_property_map' shortcode in all versions up to, and including, 4.4.2 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 Essential Real Estate WordPress plugin is vulnerable to stored XSS via the 'ere_property_map' shortcode. Authenticated attackers with contributor-level access can inject malicious JavaScript through unsanitized shortcode attributes that are not properly escaped when output, causing scripts to execute when pages containing the shortcode are accessed.

MitigationUpdate the plugin to version 4.4.3 or later which implements proper input sanitization and output escaping on shortcode attributes. Until then, restrict contributor-level access or audit existing pages for malicious shortcode usage.

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 Essential Real Estate plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Essential Real Estate' by G5plus, or check the wp-content/plugins directory for the essential-real-estate folder
    Affected if The plugin is present in the installation
  2. Check installed plugin version
    In WordPress admin, go to Plugins > Installed Plugins, find Essential Real Estate, and note the version number displayed, or read the main plugin file header for the Version field
    Affected if Version is lower than 4.4.3 (for example, 4.4.2, 4.4.1, etc.)
  3. Identify pages using the ere_property_map shortcode
    Search the WordPress database or use a search tool to find all posts, pages, and custom post types containing the [ere_property_map] shortcode. Check wp_postmeta and wp_posts tables for this shortcode string
    Affected if The shortcode is present in any published content
  4. Inspect shortcode attributes for malicious content
    For each instance of [ere_property_map] found, examine the attributes (such as map_center, zoom, height, etc.) for any unusual characters, script tags, event handlers (onclick, onerror, etc.), or encoded JavaScript payloads
    Affected if Any shortcode contains unsanitized user-supplied attributes that could execute JavaScript when the page loads
  5. Review contributor-level user accounts
    In WordPress admin, go to Users and filter by the Contributor role. Identify how many contributor accounts exist and whether any are unauthorized or compromised
    Affected if There are contributor users who could potentially author content with malicious shortcodes

The environment is affected if Essential Real Estate plugin version is below 4.4.3 AND the ere_property_map shortcode is in use with exploitable attributes, especially when contributor-level access exists.
