CVE-2026-32504: VintWood LFI Vulnerability in WordPress

CVE-2026-32504 Overview

CVE-2026-32504 is a Local File Inclusion (LFI) vulnerability in the CreativeWS VintWood WordPress theme. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include local files from the server. This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program).

Successful exploitation of this vulnerability could allow unauthenticated attackers to read sensitive files from the web server, potentially leading to information disclosure, configuration file exposure, or in some cases, remote code execution when combined with other attack techniques.

Critical Impact

Unauthenticated attackers can exploit this LFI vulnerability to read arbitrary local files on the server, potentially exposing sensitive configuration data, credentials, or enabling further attack chains including remote code execution.

Affected Products

• CreativeWS VintWood WordPress Theme versions 1.1.8 and earlier
• WordPress installations using affected VintWood theme versions

Technical Details for CVE-2026-32504

Vulnerability Analysis

This Local File Inclusion vulnerability exists due to improper validation of user-controlled input in PHP include or require statements within the VintWood WordPress theme. When a PHP application uses user-supplied input to dynamically construct file paths for inclusion, an attacker can manipulate the input to include arbitrary local files from the server's filesystem.

The vulnerability allows unauthenticated remote attackers to exploit the flaw over the network, though successful exploitation requires some complexity in crafting the attack. Once exploited, the attacker gains the ability to read sensitive files that the web server process has access to, including configuration files like wp-config.php that contain database credentials.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize and validate user input before using it in PHP file inclusion functions such as include(), require(), include_once(), or require_once(). The VintWood theme accepts filename parameters without adequate filtering, allowing path traversal sequences or direct file path specifications to be processed.

Without proper input validation, an attacker can supply malicious paths containing directory traversal sequences (e.g., ../) to navigate outside the intended directory and include arbitrary files from the server filesystem.

Attack Vector

The attack is conducted remotely over the network without requiring authentication. An attacker can send specially crafted HTTP requests containing manipulated file path parameters to the vulnerable theme components. The attacker might use path traversal techniques such as ../../etc/passwd or wrapper protocols to read local files.

Common attack payloads for LFI vulnerabilities include:

• Directory traversal sequences to access files outside the web root (e.g., ../../../../etc/passwd)
• PHP wrapper protocols such as php://filter to read PHP source code
• Log file inclusion combined with log poisoning for code execution

The vulnerability is described in detail in the Patchstack Vintwood Theme Vulnerability advisory.

Detection Methods for CVE-2026-32504

Indicators of Compromise

• Unusual HTTP requests containing path traversal sequences (../, ..%2f, ..%5c) targeting theme files
• Web server logs showing requests attempting to access system files like /etc/passwd, wp-config.php, or .htaccess
• Requests containing PHP wrapper protocols such as php://filter, php://input, or data://
• Unexpected file access patterns or error messages in PHP logs indicating failed file inclusion attempts

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in request parameters
• Monitor HTTP request logs for suspicious patterns targeting the VintWood theme directories
• Deploy file integrity monitoring to detect unauthorized access attempts to sensitive configuration files
• Analyze PHP error logs for include/require failures that may indicate exploitation attempts

Monitoring Recommendations

• Enable verbose logging on WordPress and the web server to capture detailed request information
• Set up alerting for requests containing known LFI attack patterns targeting theme components
• Monitor access to sensitive files such as wp-config.php, .htaccess, and system files
• Implement real-time log analysis to detect exploitation attempts early

How to Mitigate CVE-2026-32504

Immediate Actions Required

• Identify and audit all WordPress installations using the VintWood theme version 1.1.8 or earlier
• Consider disabling or replacing the VintWood theme with a secure alternative until a patched version is available
• Implement Web Application Firewall (WAF) rules to block LFI attack patterns
• Review web server logs for signs of exploitation attempts and conduct incident response if compromise is suspected

Patch Information

As of the publication date, the vulnerability affects VintWood theme versions through 1.1.8. Website administrators should check with CreativeWS for an updated theme version that addresses this vulnerability. Monitor the Patchstack Vintwood Theme Vulnerability advisory for patch availability updates.

Workarounds

• Replace the vulnerable VintWood theme with a secure alternative theme until a patch is released
• Implement strict WAF rules to block requests containing path traversal sequences and PHP wrapper protocols
• Restrict file permissions on sensitive files such as wp-config.php to limit exposure if LFI is exploited
• Consider using PHP open_basedir configuration to restrict the directories PHP can access
• Disable unnecessary PHP wrapper protocols in php.ini using the allow_url_include = Off directive

# PHP configuration hardening example for php.ini
# Disable remote file inclusion
allow_url_include = Off
allow_url_fopen = Off

# Restrict PHP to specific directories (adjust path as needed)
open_basedir = /var/www/html/:/tmp/

# Apache/Nginx: Block common LFI patterns via ModSecurity or similar
# SecRule REQUEST_URI "@rx \.\./" "id:1000001,phase:2,deny,status:403,msg:'Path Traversal Attempt'"
