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 xtemos WoodMart woodmart allows Object Injection.This issue affects WoodMart: from n/a through <= 8.3.8.

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

A deserialization vulnerability in the WoodMart WooCommerce theme allows attackers to inject malicious PHP objects via untrusted serialized data. This object injection can lead to remote code execution, file operations, or other attacks depending on available gadget chains in the application environment.

MitigationUpdate WoodMart to the latest version after the vendor releases a patch. If no patch is available, disable the vulnerable functionality or implement input validation to reject serialized data, replacing with safer formats like JSON.

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 WoodMart theme installation
    Check your WordPress site's wp-content/themes/ directory for the woodmart folder, or view the active theme in WordPress admin under Appearance > Themes
    Affected if WoodMart theme is present in the themes directory and active
  2. Identify installed WoodMart version
    Check the style.css file in wp-content/themes/woodmart/ for the 'Version:' header, or look in the theme's functions.php for the version constant
    Affected if The version number found is lower than the patched version released by the vendor
  3. Detect AJAX endpoints handling serialized data
    Search the theme's PHP files (particularly in the functions.php, ajax/ folder, or includes/ folder) for unserialize() function calls that process $_POST, $_GET, or $_REQUEST superglobals
    Affected if Code exists that directly deserializes data from untrusted user input without validation
  4. Check for exposed unserialize handlers
    Review AJAX action handlers in the theme - grep for 'add_action.*ajax' and examine whether any accept and unserialize serialized payload data
    Affected if Any AJAX or REST API endpoint in the theme processes serialized PHP data from client requests

Your environment is affected if the WoodMart theme is installed and the installed version has not been patched to address the deserialization vulnerability, particularly if the theme exposes endpoints that unserialize data from untrusted sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

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

Update WoodMart to the latest version after the vendor releases a patch. If no patch is available, disable the vulnerable functionality or implement input validation to reject serialized data, replacing with safer formats like JSON.

Recommended fix Moderate confidence

WoodMart theme version > 8.3.8 (latest version available from xtemos/ThemeForest)

  1. Log in to your WordPress admin dashboard
  2. Navigate to Appearance > Themes
  3. Locate the WoodMart theme
  4. Check if an update is available for the WoodMart theme
  5. If an update is available, update to the latest version which should be higher than 8.3.8
  6. After updating, verify the site still functions correctly
  7. Consider taking a full backup before performing the update
Caveat Theme updates may require child theme adjustments for custom code; always test on staging first
