CVE-2025-39467: Wanderland Path Traversal Vulnerability

CVE-2025-39467 Overview

CVE-2025-39467 is a critical Path Traversal vulnerability in the Wanderland WordPress theme by Mikado-Themes (Qode Interactive) that enables PHP Local File Inclusion (LFI). This vulnerability allows unauthenticated attackers to traverse directory structures using specially crafted `.../...//' sequences to include arbitrary PHP files from the local file system, potentially leading to remote code execution, sensitive data exposure, and complete site compromise.

Critical Impact

This vulnerability allows unauthenticated remote attackers to include arbitrary local PHP files, potentially enabling remote code execution, disclosure of sensitive configuration data, and complete WordPress site takeover without any user interaction required.

Affected Products

• Qodeinteractive Wanderland WordPress Theme versions through 1.7.1
• WordPress installations using vulnerable Wanderland theme versions
• All WordPress sites with Wanderland theme <= 1.7.1 exposed to the network

Technical Details for CVE-2025-39467

Vulnerability Analysis

This vulnerability exists due to improper input validation in the Wanderland WordPress theme's file inclusion mechanism. The theme fails to properly sanitize user-supplied input before using it in file path operations, specifically allowing the `.../...//' directory traversal sequence to bypass standard path restrictions.

When a user-controlled parameter containing traversal sequences is processed, the application fails to adequately filter or normalize the path. This allows attackers to escape the intended directory structure and include PHP files from arbitrary locations on the server's file system. The vulnerability is classified under CWE-35 (Path Traversal) and enables PHP Local File Inclusion.

The attack requires no authentication and can be executed remotely over the network, making it highly exploitable. Successful exploitation can lead to arbitrary code execution if attackers can include malicious PHP content, or information disclosure by including sensitive configuration files.

Root Cause

The root cause of CVE-2025-39467 is insufficient input validation and sanitization of file path parameters within the Wanderland theme. The application accepts user input that is directly incorporated into file system operations without properly neutralizing special path traversal characters. The .../...//' sequence specifically bypasses basic filtering mechanisms that may only check for standard ../` patterns, allowing directory escape and inclusion of files outside the intended scope.

Attack Vector

The vulnerability is exploitable via network-based requests to the WordPress installation running the vulnerable Wanderland theme. An unauthenticated attacker can craft HTTP requests containing malicious path traversal sequences targeting theme endpoints that perform file inclusion operations.

The attack flow typically involves:

1. Identifying a WordPress site using the Wanderland theme <= 1.7.1
2. Crafting a request with .../...//' sequences in vulnerable parameters
3. Targeting sensitive files such as wp-config.php for information disclosure
4. Potentially including uploaded files or log files containing attacker-controlled PHP code for remote code execution

Detection Methods for CVE-2025-39467

Indicators of Compromise

• HTTP requests containing .../...//' or similar obfuscated path traversal sequences in URL parameters or POST data
• Access logs showing requests to theme endpoints with traversal patterns targeting sensitive files like wp-config.php or /etc/passwd
• Unusual file access patterns in PHP error logs indicating attempts to include files outside the theme directory
• Unexpected web server errors related to file inclusion or permission denied messages

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns including obfuscated variants like .../...//'
• Monitor web server access logs for suspicious requests containing directory traversal sequences targeting the Wanderland theme
• Deploy file integrity monitoring on critical WordPress files to detect unauthorized access or modifications
• Use intrusion detection systems (IDS) configured with signatures for LFI exploitation attempts

Monitoring Recommendations

• Enable detailed logging on WordPress installations and review logs for path traversal patterns
• Configure alerting for requests containing file inclusion indicators such as references to wp-config.php, ../, or PHP file paths
• Monitor for unusual PHP process activity that may indicate successful code execution via LFI

How to Mitigate CVE-2025-39467

Immediate Actions Required

• Update the Wanderland theme to a patched version above 1.7.1 immediately
• If no patch is available, consider temporarily deactivating the Wanderland theme until a fix is released
• Implement WAF rules to block path traversal patterns at the network perimeter
• Review server logs for evidence of exploitation attempts

Patch Information

Organizations using the Wanderland WordPress theme should check for available updates from Qode Interactive or Mikado-Themes. The vulnerability affects all versions through 1.7.1. Monitor the Patchstack advisory for patch availability and update information.

Workarounds

• Deploy a Web Application Firewall with rules blocking LFI and path traversal attack patterns
• Restrict PHP file inclusion capabilities through php.ini settings such as disabling allow_url_include and limiting open_basedir
• Implement strict file permission controls to limit the web server's access to sensitive system files
• Consider switching to an alternative WordPress theme that is actively maintained and patched

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

# Restrict PHP file operations to specific directories
open_basedir = /var/www/html:/tmp

# Disable dangerous PHP functions
disable_functions = exec,passthru,shell_exec,system,proc_open,popen
