CVE-2026-25017: NaturaLife Extensions LFI Vulnerability

CVE-2026-25017 Overview

CVE-2026-25017 is a Local File Inclusion (LFI) vulnerability affecting the NaturaLife Extensions WordPress plugin developed by stmcan. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include arbitrary local files from the server's filesystem. This can lead to sensitive information disclosure, configuration file exposure, and potentially remote code execution when combined with other attack techniques.

Critical Impact
Attackers can exploit this LFI vulnerability to read sensitive server files, potentially exposing database credentials, WordPress configuration details, and other critical system information. Under certain conditions, this could be chained with other vulnerabilities to achieve remote code execution.

Affected Products

NaturaLife Extensions plugin version 2.1 and earlier
WordPress installations running vulnerable versions of the NaturaLife Extensions plugin

Technical Details for CVE-2026-25017

Vulnerability Analysis

The vulnerability exists due to improper sanitization and validation of user-controlled input that is subsequently used in PHP include() or require() statements within the NaturaLife Extensions plugin. This weakness is classified as CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program).

When a PHP application uses unsanitized user input to construct file paths for inclusion, attackers can manipulate the path to include unintended files. In this case, the plugin fails to properly validate filename parameters, enabling path traversal sequences (such as ../) to navigate the directory structure and include sensitive files like wp-config.php, /etc/passwd, or log files containing session tokens.

The network-based attack vector means that exploitation can occur remotely without authentication. However, successful exploitation requires the attacker to overcome certain conditions, making the attack complexity higher than trivial exploits. Once exploited, the vulnerability can compromise the confidentiality, integrity, and availability of the affected system.

Root Cause

The root cause of this vulnerability is insufficient input validation in the NaturaLife Extensions plugin's file inclusion logic. The plugin accepts user-controlled parameters that are directly passed to PHP's include() or require() functions without adequate sanitization. Specifically, the code fails to:

Validate that the requested file exists within an allowed directory
Strip or reject path traversal sequences (../, ..\\)
Implement a whitelist of allowable files for inclusion
Use absolute paths with proper base directory restrictions

Attack Vector

The vulnerability is exploitable over the network, requiring no prior authentication. An attacker can craft malicious HTTP requests containing path traversal sequences in vulnerable parameters. By manipulating the file path, the attacker can traverse directories and include arbitrary files accessible to the web server process.

Typical exploitation scenarios include reading the WordPress configuration file (wp-config.php) to obtain database credentials, accessing server configuration files, or including log files that may contain injected PHP code for achieving remote code execution through log poisoning techniques.

Detection Methods for CVE-2026-25017

Indicators of Compromise

Unusual HTTP requests containing path traversal patterns (e.g., ../, ..%2f, ..%5c) targeting the NaturaLife Extensions plugin endpoints
Web server access logs showing repeated attempts to access sensitive files through plugin parameters
Error logs indicating failed file inclusion attempts or warnings about non-existent files
Unexpected access patterns to WordPress configuration files or system files

Detection Strategies

Deploy Web Application Firewall (WAF) rules to detect and block path traversal sequences in request parameters
Monitor access logs for requests containing ../ patterns targeting plugin directories
Implement file integrity monitoring on critical configuration files like wp-config.php
Configure intrusion detection systems to alert on LFI attack signatures

Monitoring Recommendations

Enable verbose logging for the WordPress application and web server
Monitor for unusual file access patterns from the web server process
Set up alerts for access attempts to sensitive system files from web application contexts
Review plugin activity logs for anomalous file inclusion operations

How to Mitigate CVE-2026-25017

Immediate Actions Required

Update the NaturaLife Extensions plugin to the latest patched version immediately
If no patch is available, consider disabling or removing the NaturaLife Extensions plugin until a fix is released
Implement WAF rules to block path traversal attempts targeting the vulnerable plugin
Review server logs for evidence of exploitation attempts
Verify the integrity of wp-config.php and other critical configuration files

Patch Information

Security researchers have identified this vulnerability in NaturaLife Extensions versions through 2.1. Check the PatchStack vulnerability database for the latest patch information and updates from the plugin developer. Website administrators should ensure they are running the most current version of the plugin with all security patches applied.

Workarounds

Temporarily disable the NaturaLife Extensions plugin if an immediate patch is not available
Implement server-level restrictions using .htaccess or web server configuration to block suspicious request patterns
Configure PHP's open_basedir directive to restrict file inclusion to specific directories
Use security plugins that provide virtual patching capabilities for known WordPress vulnerabilities
Place the WordPress installation behind a WAF configured to detect and block LFI attack patterns

bash

# Example .htaccess rules to block path traversal attempts
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{QUERY_STRING} (\.\./|\.\.\\) [NC,OR]
    RewriteCond %{QUERY_STRING} (\.\.%2f|\.\.%5c) [NC]
    RewriteRule .* - [F,L]
</IfModule>
