CVE-2026-24608: Laurent Core PHP File Inclusion Flaw

CVE-2026-24608 Overview

CVE-2026-24608 is a PHP Local File Inclusion (LFI) vulnerability affecting the Laurent Core WordPress plugin developed by Elated-Themes. This vulnerability stems from improper control of filename parameters in PHP include/require statements, allowing authenticated attackers to include arbitrary local files on the server. Successful exploitation could lead to sensitive information disclosure, configuration file access, or potentially escalate to remote code execution through log poisoning or other chained attack techniques.

Critical Impact

Authenticated attackers can leverage this Local File Inclusion vulnerability to read sensitive server files, potentially exposing database credentials, WordPress configuration data, and other confidential information stored on the web server.

Affected Products

• Elated-Themes Laurent Core plugin version 2.4.1 and earlier
• WordPress installations running vulnerable versions of the laurent-core plugin

Technical Details for CVE-2026-24608

Vulnerability Analysis

This vulnerability is classified as CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Laurent Core plugin fails to properly sanitize user-controlled input that is subsequently used in PHP include(), require(), include_once(), or require_once() statements. When an authenticated user can manipulate the filename parameter, they can traverse the directory structure and include files outside the intended scope.

The attack can be conducted remotely over the network, though it requires authenticated access to the WordPress installation. The vulnerability affects the confidentiality, integrity, and availability of the system, as attackers may be able to read sensitive configuration files, potentially modify server behavior through log injection, or cause service disruptions.

Root Cause

The root cause lies in insufficient input validation and sanitization of user-supplied parameters before they are passed to PHP's file inclusion functions. The plugin does not adequately filter directory traversal sequences (such as ../) or validate that the requested file resides within an allowed directory. This allows authenticated users to escape the intended directory context and include arbitrary files from the server's filesystem.

Attack Vector

The attack is network-based and requires low-privileged authenticated access to the WordPress site. An attacker would craft a malicious request containing directory traversal sequences in the vulnerable parameter to include sensitive local files such as /etc/passwd, wp-config.php, or application log files. The technical complexity is considered high due to the specific conditions required for successful exploitation.

The vulnerability can be exploited by manipulating file path parameters within plugin requests, using path traversal sequences like ../ to navigate to sensitive system files. For example, an attacker might target the WordPress configuration file to extract database credentials or include log files where malicious PHP code has been previously injected. For detailed technical analysis, refer to the Patchstack Vulnerability Report.

Detection Methods for CVE-2026-24608

Indicators of Compromise

• Unusual HTTP requests containing path traversal patterns (../, ..%2f, ..%252f) targeting Laurent Core plugin endpoints
• Access log entries showing requests for sensitive files like wp-config.php, /etc/passwd, or application logs through plugin parameters
• Error logs indicating file inclusion failures for non-existent paths outside the plugin directory
• Unexpected reads of configuration files or system files from the web server process

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block path traversal sequences in request parameters
• Monitor WordPress plugin activity logs for suspicious file access patterns associated with the laurent-core plugin
• Implement file integrity monitoring (FIM) to detect unauthorized access to sensitive configuration files
• Review Apache/Nginx access logs for anomalous requests containing encoded traversal sequences targeting the Laurent Core plugin

Monitoring Recommendations

• Enable verbose logging for the WordPress installation and monitor for LFI-related error messages
• Configure SIEM alerts for path traversal patterns in web server logs, particularly requests to /wp-content/plugins/laurent-core/
• Implement behavioral analysis to detect authenticated users attempting to access files outside normal application scope
• Monitor for unusual outbound data transfers that may indicate successful extraction of sensitive configuration data

How to Mitigate CVE-2026-24608

Immediate Actions Required

• Audit your WordPress installations and identify all instances running the Laurent Core plugin version 2.4.1 or earlier
• Consider temporarily deactivating the laurent-core plugin until a patched version is available and verified
• Implement WAF rules to block requests containing path traversal sequences targeting the vulnerable plugin
• Review access logs for evidence of exploitation attempts and investigate any suspicious activity

Patch Information

At the time of publication, administrators should monitor the official Elated-Themes release channels and the WordPress plugin repository for security updates addressing this vulnerability. Review the Patchstack Vulnerability Report for the latest remediation guidance and patch availability information.

Workarounds

• Implement strict input validation at the web server level using ModSecurity or similar WAF solutions to filter path traversal attempts
• Restrict file system permissions to limit the web server's ability to read sensitive files outside the WordPress directory
• Enable PHP open_basedir restrictions to confine PHP file operations to the WordPress installation directory
• Apply the principle of least privilege by limiting authenticated user capabilities and removing unnecessary user accounts

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

# PHP open_basedir configuration in .htaccess or php.ini
# Restrict PHP file access to WordPress directory
php_admin_value open_basedir /var/www/html/wordpress/:/tmp/
