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
Unauthenticated Cross Site Scripting (XSS) in Real Estate 7 <= 3.5.9 versions.

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 · moderate confidence

Unauthenticated Cross Site Scripting (XSS) vulnerability in Real Estate 7 theme versions 3.5.9 and below allows remote attackers to inject malicious JavaScript code into the web application without requiring authentication.

MitigationUpgrade Real Estate 7 to a version newer than 3.5.9; as a temporary measure, implement proper input sanitization and output encoding on user-supplied data.

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 Real Estate 7 theme is installed
    Inspect the theme directory or WordPress admin theme list to verify Real Estate 7 theme is active on the WordPress site
    Affected if Real Estate 7 theme is present and active
  2. Identify the installed theme version
    Check the theme style.css header or version.php file within the Real Estate 7 theme directory for the Version: field
    Affected if The version listed is 3.5.9 or lower
  3. Compare version against affected range
    Compare your installed version number to the affected range of 3.5.9 and below
    Affected if The installed version is 3.5.9 or any version lower than 3.5.9
  4. Locate unauthenticated input points
    Review theme templates and PHP files that process user-supplied data from HTTP request parameters without authentication gates (such as search forms, contact forms, or parameter-handling code)
    Affected if The theme processes user input from unauthenticated sources in its PHP files
  5. Verify output encoding on input handlers
    Inspect the PHP code handling the unauthenticated inputs for use of output encoding functions (htmlspecialchars, esc_html, esc_attr) before rendering user data
    Affected if User-supplied data is rendered to HTML without proper encoding functions, indicating the XSS vulnerability is present

A site is affected if it runs Real Estate 7 theme version 3.5.9 or lower and processes unauthenticated user input without sanitization or output encoding.

Mitigation

Upgrade Real Estate 7 to a version newer than 3.5.9; as a temporary measure, implement proper input sanitization and output encoding on user-supplied data.
