CVE-2025-15470: Eleganzo WordPress Path Traversal Flaw

CVE-2025-15470 Overview

The Eleganzo theme for WordPress is vulnerable to arbitrary directory deletion due to insufficient path validation in the akd_required_plugin_callback function in all versions up to, and including, 1.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary directories on the server, including the WordPress root directory.

Critical Impact

Authenticated attackers with minimal privileges (Subscriber-level) can delete arbitrary directories on the server, potentially destroying entire WordPress installations or critical system directories.

Affected Products

• Eleganzo WordPress Theme versions up to and including 1.2
• WordPress installations using vulnerable Eleganzo theme versions

Technical Details for CVE-2025-15470

Vulnerability Analysis

This vulnerability is classified as CWE-22 (Path Traversal), which occurs when user-supplied input is used to construct file or directory paths without proper validation. The vulnerable function akd_required_plugin_callback in the Eleganzo WordPress theme fails to adequately sanitize or validate directory paths before performing deletion operations. This allows authenticated users with even the lowest privilege level (Subscriber) to craft malicious requests that traverse outside the intended directory scope and delete arbitrary directories on the server.

The attack is network-accessible and requires no user interaction, though it does require a valid WordPress account with at least Subscriber-level permissions. The vulnerability primarily impacts the integrity of the system, as attackers can delete critical directories including the WordPress root directory itself, effectively destroying the website.

Root Cause

The root cause of this vulnerability lies in insufficient path validation within the akd_required_plugin_callback function located in welcome.php at approximately line 96. The function accepts user-controlled input that specifies a directory path for deletion operations but fails to implement proper path canonicalization, directory traversal prevention, or whitelist-based validation to ensure the specified path remains within expected boundaries.

Attack Vector

The attack vector involves an authenticated user sending a crafted request to the vulnerable AJAX callback function. By manipulating the directory path parameter with path traversal sequences (such as ../), an attacker can escape the intended directory structure and target arbitrary directories on the server. Since the function operates with the web server's filesystem permissions, any directory writable by the web server process can be deleted.

The vulnerability can be exploited remotely over the network by any authenticated WordPress user with Subscriber-level access or higher. The attacker constructs a malicious request targeting the akd_required_plugin_callback AJAX action with a crafted path parameter containing directory traversal sequences to reference directories outside the theme's expected scope.

Detection Methods for CVE-2025-15470

Indicators of Compromise

• Unexpected AJAX requests to admin-ajax.php with action akd_required_plugin_callback from low-privilege users
• Server logs showing directory deletion operations in unexpected locations
• Missing directories or files outside the theme's expected scope
• WordPress installation files or directories unexpectedly deleted

Detection Strategies

• Monitor WordPress AJAX endpoints for requests to akd_required_plugin_callback action, especially from Subscriber-level accounts
• Implement file integrity monitoring to detect unauthorized directory deletions
• Review web server access logs for suspicious patterns involving the Eleganzo theme's AJAX handlers
• Enable WordPress debug logging to capture unusual theme activity

Monitoring Recommendations

• Configure real-time alerting for filesystem changes in critical WordPress directories
• Implement user activity logging to track AJAX requests by privilege level
• Deploy web application firewall (WAF) rules to detect path traversal patterns in requests
• Monitor for unusual account activity, particularly newly created Subscriber accounts

How to Mitigate CVE-2025-15470

Immediate Actions Required

• Disable or remove the Eleganzo theme if version 1.2 or earlier is installed
• Audit server directories for any signs of unauthorized deletions
• Review user accounts for suspicious Subscriber-level accounts that may have been created for exploitation
• Implement web application firewall rules to block path traversal attempts

Patch Information

Users should check for updated versions of the Eleganzo theme that address this vulnerability. Refer to the Wordfence Vulnerability Report for the latest patch information and vendor advisories. Until a patch is available, the theme should be deactivated and removed from production environments.

Workarounds

• Deactivate and delete the Eleganzo theme from WordPress installations immediately
• Restrict Subscriber account registration if not required for business operations
• Implement additional access controls through .htaccess or server configuration to restrict access to theme AJAX handlers
• Deploy a WordPress security plugin with path traversal detection capabilities

# Configuration example - Disable the vulnerable theme via WP-CLI
wp theme deactivate eleganzo
wp theme delete eleganzo

# Restrict AJAX access at the server level (Apache example)
# Add to .htaccess to block specific AJAX actions
# <IfModule mod_rewrite.c>
#   RewriteEngine On
#   RewriteCond %{QUERY_STRING} action=akd_required_plugin_callback [NC]
#   RewriteRule ^wp-admin/admin-ajax\.php$ - [F,L]
# </IfModule>
