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
Deserialization of Untrusted Data vulnerability in Edge-Themes Gracey gracey allows Object Injection.This issue affects Gracey: from n/a through < 1.4.

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

This is a PHP Object Injection vulnerability in the Gracey WordPress theme from Edge-Themes. The theme deserializes untrusted data without proper validation, allowing attackers to inject malicious PHP objects. If exploitable, this could lead to remote code execution, file manipulation, or SQL injection depending on available classes and magic methods in the application context.

MitigationUpgrade Gracey theme to version 1.4 or later. If patching manually, replace all unsafe deserialization (unserialize()) calls with safer alternatives like json_decode() and implement strict input validation before any deserialization occurs.

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. Locate Gracey theme installation directory
    In your WordPress site, navigate to wp-content/themes/ and identify the gracey folder. Note the full path for subsequent checks.
    Affected if The gracey theme folder exists in the WordPress themes directory.
  2. Determine installed Gracey theme version
    Open the theme's style.css file (typically at wp-content/themes/gracey/style.css) and locate the 'Version:' header in the file header comments. Compare this version number to the fixed version 1.4.
    Affected if The installed version is lower than 1.4.
  3. Identify unsafe deserialization calls
    Search all PHP files in the gracey theme directory for 'unserialize(' function calls. Common locations include functions.php, classes, or AJAX handlers. Use grep or a file search: grep -r "unserialize(" wp-content/themes/gracey/
    Affected if The theme contains any unserialize() calls without prior json_decode() or input validation.
  4. Verify if user input reaches deserialization
    Examine the code around each unserialize() call found. Trace back the data source - check if the input comes from $_GET, $_POST, $_REQUEST, $_COOKIE, or database values without sanitization. Look for patterns like unserialize($_POST['...']) or unserialize($data_from_db).
    Affected if User-controllable data (request parameters, database fields) flows directly into unserialize() without validation.
  5. Check for magic method gadgets
    Review the theme and active plugins for PHP classes with __wakeup, __destruct, __toString, or __call magic methods. These could be chained for exploitation if object injection is possible. Search for class definitions containing these magic methods.
    Affected if The environment contains classes with exploitable magic methods that could be triggered via injected objects.

You are affected if the Gracey theme version is below 1.4 AND your site contains unserialize() calls that process untrusted user input without validation.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Gracey theme to version 1.4 or later. If patching manually, replace all unsafe deserialization (unserialize()) calls with safer alternatives like json_decode() and implement strict input validation before any deserialization occurs.

Recommended fix Moderate confidence

Gracey theme version 1.4 or later

  1. Backup your WordPress site database and files before making any changes
  2. Navigate to Appearance > Themes in WordPress admin dashboard
  3. If a newer version of Gracey theme (version 1.4 or higher) is available in the WordPress theme repository, update directly through the admin
  4. Alternatively, download Gracey version 1.4 or later from the theme vendor and upload via Appearance > Themes > Add New > Upload Theme
  5. After updating, clear any caching plugins and verify the site functionality works correctly
  6. Review theme settings after upgrade as some configurations may need reapplication
Caveat WordPress theme updates may override custom child theme modifications or custom CSS; review any customizations after upgrading
