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 Jthemes Prestige prestige allows Object Injection.This issue affects Prestige: from n/a through < 1.4.1.

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

The Jthemes Prestige theme below version 1.4.1 is vulnerable to PHP Object Injection via deserialization of untrusted data. Attackers can exploit this by sending crafted serialized PHP objects to vulnerable endpoints, potentially achieving remote code execution if magic methods exist in the theme or associated plugins.

MitigationUpgrade the Prestige theme to version 1.4.1 or later. If immediate upgrade is not possible, disable the theme and review access to any PHP unserialize() calls that process user input.

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. Identify installed Prestige theme version
    Locate the theme's version file (typically in style.css header, version.php, or theme config) and note the version number reported
    Affected if Version is below 1.4.1 (for example, 1.4.0, 1.3.x, etc.)
  2. Locate PHP unserialize() calls in theme files
    Search theme source files for 'unserialize' function calls and review which ones process data from $_GET, $_POST, $_REQUEST, or HTTP headers
    Affected if The theme contains unserialize() calls that process user-supplied input without prior validation
  3. Identify endpoints accepting serialized data
    Review theme PHP files for endpoints that accept and process serialized data from HTTP requests, including AJAX handlers or form processors
    Affected if User-accessible endpoints exist that accept and deserialize data from request parameters
  4. Check for magic methods in theme or plugins
    Search theme and active plugin files for magic methods (such as __destruct, __wakeup, __invoke, __toString) that could be chained for code execution
    Affected if Magic methods are present in the theme or associated plugins that could be triggered via object injection

User is affected if the Prestige theme version is below 1.4.1 AND the theme processes untrusted serialized PHP data through accessible unserialize() calls.

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

Upgrade the Prestige theme to version 1.4.1 or later. If immediate upgrade is not possible, disable the theme and review access to any PHP unserialize() calls that process user input.

Recommended fix High confidence

Prestige version 1.4.1 or latest available

  1. 1. Backup your entire WordPress site and database before making any changes
  2. 2. Obtain Prestige theme version 1.4.1 or the latest available version from the official Jthemes source
  3. 3. Update the Prestige theme through your WordPress dashboard (Appearance > Themes) or via FTP/SFTP upload
  4. 4. Verify the update was successful by checking the installed theme version
  5. 5. Test critical site functionality to ensure the update did not break any features
Caveat Review the theme changelog for any breaking changes or deprecated features before upgrading
