CVE-2026-24609: Laurent Theme Local File Inclusion Flaw

CVE-2026-24609 Overview

CVE-2026-24609 is a Local File Inclusion (LFI) vulnerability affecting the Laurent WordPress theme developed by Elated-Themes. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing authenticated attackers to include arbitrary local files on the target system. This type of vulnerability (CWE-98) can lead to sensitive information disclosure, configuration file exposure, and in certain conditions, remote code execution through log poisoning or other advanced exploitation techniques.

Critical Impact

Authenticated attackers with low privileges can exploit this vulnerability to read sensitive files from the server, potentially exposing database credentials, WordPress configuration files, and other critical system information.

Affected Products

• Elated-Themes Laurent WordPress Theme versions through 3.1
• WordPress installations running vulnerable Laurent theme versions

Technical Details for CVE-2026-24609

Vulnerability Analysis

The Laurent WordPress theme fails to properly sanitize user-supplied input before using it in PHP include or require statements. This improper control of filename parameters allows attackers to manipulate the file path and include arbitrary local files from the web server's file system.

The vulnerability requires network access and authentication with low privileges, though exploitation requires high attack complexity. Successful exploitation can result in full compromise of confidentiality, integrity, and availability of the affected system. An attacker could read sensitive configuration files such as wp-config.php, access log files that may contain sensitive data, or potentially achieve code execution through techniques like log file poisoning.

Root Cause

The root cause is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The theme code accepts user input that is insufficiently validated before being passed to PHP's file inclusion functions. Without proper path traversal filtering and whitelist validation, attackers can escape the intended directory context and access arbitrary files on the server.

Attack Vector

The attack is network-based, requiring the attacker to have authenticated access to the WordPress installation with at least low-level privileges. The attacker manipulates a parameter value to include path traversal sequences (such as ../) combined with a target file path. The PHP interpreter then includes the specified file, disclosing its contents to the attacker or executing it if it contains PHP code.

The vulnerability mechanism involves manipulating include/require parameters to traverse directories and access sensitive files. Attackers typically target configuration files like wp-config.php or system files like /etc/passwd. For detailed technical information, see the Patchstack security advisory.

Detection Methods for CVE-2026-24609

Indicators of Compromise

• Unusual file access patterns in web server logs showing path traversal sequences (../, ..%2f, %2e%2e/)
• HTTP requests containing file path references to system files or WordPress configuration files
• Log entries showing attempts to access wp-config.php, /etc/passwd, or other sensitive files through theme endpoints
• Unexpected access to theme-related URLs with manipulated parameters

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in HTTP requests
• Monitor web server access logs for requests containing encoded or unencoded directory traversal sequences
• Deploy file integrity monitoring on critical configuration files to detect unauthorized access attempts
• Enable verbose logging for PHP file operations to capture suspicious include/require activities

Monitoring Recommendations

• Configure SIEM rules to alert on path traversal patterns targeting WordPress theme directories
• Establish baseline monitoring for file access patterns within the WordPress installation
• Monitor for anomalous authenticated user activity that may indicate credential compromise or privilege abuse
• Implement real-time alerting for access attempts to sensitive configuration files

How to Mitigate CVE-2026-24609

Immediate Actions Required

• Verify if the Laurent theme is installed by checking wp-content/themes/ directory for the laurent folder
• If vulnerable version (3.1 or earlier) is detected, immediately disable or remove the theme
• Review web server logs for evidence of exploitation attempts
• Check for unauthorized changes to WordPress configuration or uploaded files
• Apply updated theme version when available from Elated-Themes

Patch Information

As of the last NVD update on 2026-01-26, users should check the Patchstack vulnerability database for the latest patch status and remediation guidance from Elated-Themes. Ensure your WordPress theme is updated to a version newer than 3.1 once a patched release becomes available.

Workarounds

• Temporarily switch to a different WordPress theme until a patched version of Laurent is available
• Implement WAF rules to block requests containing path traversal sequences targeting theme files
• Restrict file system permissions to limit PHP's ability to read sensitive files outside the web root
• Use PHP's open_basedir directive to restrict file access to the WordPress installation directory

# Apache .htaccess rule to block path traversal attempts
RewriteEngine On
RewriteCond %{QUERY_STRING} (\.\./|\.\.%2f|%2e%2e/) [NC]
RewriteRule .* - [F,L]

# PHP open_basedir restriction (php.ini)
open_basedir = /var/www/html/wordpress/:/tmp/
