CVE-2026-28014: Translogic Theme File Inclusion Flaw

CVE-2026-28014 Overview

CVE-2026-28014 is a Local File Inclusion (LFI) vulnerability affecting the ThemeREX Translogic WordPress theme. The vulnerability stems from improper control of filename parameters in PHP include/require statements (CWE-98), allowing attackers to include arbitrary local files from the server filesystem.

This vulnerability can enable attackers to read sensitive configuration files, access credentials stored on the server, or potentially chain with other techniques to achieve remote code execution through log poisoning or other file-based attack vectors.

Critical Impact

Attackers can exploit this LFI vulnerability to read sensitive files including wp-config.php, potentially exposing database credentials and WordPress security keys, or leverage it for further system compromise through file inclusion chains.

Affected Products

• ThemeREX Translogic WordPress Theme versions through 1.2.11

Technical Details for CVE-2026-28014

Vulnerability Analysis

This vulnerability exists due to improper validation and sanitization of user-controlled input that is subsequently used in PHP file inclusion functions such as include(), include_once(), require(), or require_once(). The Translogic theme fails to properly restrict the file paths that can be included, allowing path traversal sequences to access files outside the intended directory structure.

Local File Inclusion vulnerabilities in WordPress themes are particularly dangerous because they can expose the wp-config.php file, which contains database credentials, authentication keys, and other sensitive configuration data. Additionally, if an attacker can control any file content on the server (through uploads, logs, or other means), they may escalate this vulnerability to achieve remote code execution.

Root Cause

The root cause is classified as CWE-98: Improper Control of Filename for Include/Require Statement in PHP Program. The theme does not adequately sanitize user-supplied input before passing it to PHP file inclusion functions. This allows directory traversal sequences such as ../ to be injected, enabling access to files outside the web application's root directory.

Attack Vector

The attack is executed by manipulating request parameters that control which files are included by the PHP application. An attacker crafts malicious input containing path traversal sequences to navigate the filesystem and include sensitive files.

A typical exploitation scenario involves:

1. Identifying a vulnerable parameter in the Translogic theme that accepts file path input
2. Injecting path traversal sequences (e.g., ../../../../etc/passwd or ../../../wp-config.php)
3. The server processes the malicious path and includes the targeted file
4. File contents are returned to the attacker or parsed as PHP code

Detection Methods for CVE-2026-28014

Indicators of Compromise

• Unusual HTTP requests containing path traversal patterns (../, ..%2f, %2e%2e/) targeting theme files
• Access log entries showing attempts to include system files like /etc/passwd or wp-config.php
• Unexpected file access patterns in PHP error logs
• Requests to Translogic theme endpoints with suspicious file path parameters

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal sequences in request parameters
• Monitor web server access logs for patterns indicating LFI attempts targeting the Translogic theme directory
• Deploy file integrity monitoring on sensitive configuration files to detect unauthorized access
• Configure intrusion detection systems to alert on common LFI payload patterns

Monitoring Recommendations

• Enable verbose logging for PHP applications to capture file inclusion attempts
• Set up real-time alerting for access to sensitive files such as wp-config.php and /etc/passwd
• Monitor for anomalous traffic patterns to WordPress theme directories
• Implement SentinelOne Singularity Platform for endpoint detection and response to identify post-exploitation activity

How to Mitigate CVE-2026-28014

Immediate Actions Required

• Update the ThemeREX Translogic theme to a patched version if one is available from the vendor
• If no patch is available, consider temporarily disabling or replacing the Translogic theme
• Implement WAF rules to block path traversal attempts at the network perimeter
• Restrict file permissions on sensitive configuration files to minimize exposure
• Review server logs for any historical exploitation attempts

Patch Information

At the time of publication, affected versions include Translogic through version 1.2.11. Administrators should check ThemeREX for updated versions addressing this vulnerability. For the latest patch information and vulnerability details, consult the Patchstack WordPress Vulnerability Report.

Workarounds

• Deploy a Web Application Firewall with rules blocking common LFI patterns and path traversal sequences
• Use PHP security configurations such as open_basedir to restrict file access to the web root
• Disable unused PHP functions that could be leveraged in exploitation chains
• Implement network segmentation to limit lateral movement in case of compromise
• Consider using WordPress security plugins that provide additional input validation and monitoring

# Example Apache ModSecurity rule to block path traversal attempts
SecRule REQUEST_URI|ARGS|REQUEST_BODY "@rx (\.\./|\.\.\\)" \
    "id:1001,phase:2,deny,status:403,log,msg:'Path Traversal Attempt Blocked'"

# PHP configuration to restrict file access (add to php.ini or .htaccess)
# open_basedir = /var/www/html/:/tmp/
