CVE-2025-14042: WordPress Car Dealership Theme XSS Flaw

CVE-2025-14042 Overview

CVE-2025-14042 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the Automotive Car Dealership Business WordPress Theme. The flaw exists in the project_details custom field used within Portfolio Items. All versions through 13.4.1 are affected. Authenticated users with contributor-level access or higher can inject arbitrary JavaScript that executes when other users view the affected page. The vulnerability is classified under CWE-79 and stems from insufficient input sanitization and missing output escaping on user-supplied attributes.

Critical Impact
Authenticated contributors can persist malicious scripts in WordPress pages, enabling session theft, administrative action hijacking, and redirection of site visitors to attacker-controlled infrastructure.

Affected Products

Automotive Car Dealership Business WordPress Theme — all versions up to and including 13.4.1
WordPress sites using the project_details custom field within Portfolio Items
Distributed via ThemeForest

Technical Details for CVE-2025-14042

Vulnerability Analysis

The vulnerability resides in how the theme processes the project_details custom field within Portfolio Items. When a contributor submits content into this field, the theme stores the supplied attributes without sufficient sanitization. The theme then renders these attributes back into page output without proper escaping, permitting script execution in the viewer's browser. Because the payload persists in the database, every visitor to the affected page triggers the injected script. This represents a classic Stored XSS pattern as described in CWE-79.

Root Cause

The theme fails to apply WordPress core sanitization functions such as sanitize_text_field() or wp_kses() when accepting attribute values for project_details. It also omits esc_attr() or esc_html() calls during rendering. This dual failure on both input and output allows arbitrary HTML and JavaScript constructs to survive the storage and rendering pipeline intact.

Attack Vector

Exploitation requires authenticated access at contributor level or higher. A contributor edits or creates a Portfolio Item and injects script content into the project_details custom field. The payload is saved to the WordPress database. When any user — including administrators — views the affected page, the script executes within their browser session under the site's origin. Refer to the Wordfence Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-14042

Indicators of Compromise

Portfolio Item entries containing <script>, onerror=, onload=, or javascript: tokens within project_details post meta values
Unexpected outbound requests from visitor browsers to unfamiliar third-party domains when loading Portfolio pages
New or modified contributor accounts immediately followed by Portfolio Item edits
Administrative session cookies appearing in web server referrer logs or external telemetry

Detection Strategies

Query the wp_postmeta table for meta_key = 'project_details' and inspect values for HTML or JavaScript syntax
Review WordPress audit logs for Portfolio Item create or update events from contributor-tier accounts
Deploy a web application firewall rule that inspects POST bodies targeting /wp-admin/post.php for script payloads in custom fields
Monitor browser-side Content Security Policy violation reports for inline script blocks originating from theme-rendered pages

Monitoring Recommendations

Alert on creation of new contributor or author accounts followed by Portfolio activity within short time windows
Track outbound DNS queries from end-user browsers visiting WordPress Portfolio pages for anomalous destinations
Enable WordPress debug logging and forward wp-content/debug.log entries to a centralized logging platform for correlation

How to Mitigate CVE-2025-14042

Immediate Actions Required

Audit all existing Portfolio Items for malicious content in the project_details field and remove any injected scripts
Restrict contributor-level account creation and review existing low-privilege users for legitimacy
Apply a web application firewall ruleset that blocks script tags and event handler attributes in WordPress custom field submissions
Implement a strict Content Security Policy that disallows inline scripts on Portfolio pages

Patch Information

At the time of NVD publication on 2026-05-29, no fixed version had been identified beyond 13.4.1. Site administrators should monitor the ThemeForest product page and the Wordfence Vulnerability Report for an updated theme release addressing the sanitization gap.

Workarounds

Temporarily disable the Portfolio Items post type if it is not essential to site operation
Revoke contributor and author privileges from non-essential accounts until a patched theme version is available
Add a server-side mu-plugin that hooks save_post to sanitize project_details post meta via wp_kses_post() before persistence
Enforce two-factor authentication for all accounts at contributor level and above to reduce account takeover risk

bash

# Example: identify potentially malicious project_details entries
wp db query "SELECT post_id, meta_value FROM wp_postmeta \
  WHERE meta_key = 'project_details' \
  AND (meta_value LIKE '%<script%' \
       OR meta_value LIKE '%onerror=%' \
       OR meta_value LIKE '%javascript:%');"
