CVE-2025-69342: Calafate Path Traversal Vulnerability

CVE-2025-69342 Overview

CVE-2025-69342 is a Local File Inclusion (LFI) vulnerability affecting the Calafate WordPress theme developed by VanKarWai. This vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing authenticated attackers to include arbitrary local files from the server. When exploited, this flaw can lead to sensitive information disclosure, authentication bypass, and potentially remote code execution if combined with other attack techniques.

Critical Impact

Authenticated attackers can leverage this LFI vulnerability to read sensitive server files, potentially exposing configuration data, credentials, and enabling further exploitation through log poisoning or other chained attacks.

Affected Products

• Calafate WordPress Theme versions through 1.7.7
• WordPress installations using vulnerable Calafate theme versions
• Web servers hosting affected WordPress sites

Technical Details for CVE-2025-69342

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Calafate WordPress theme fails to properly validate or sanitize user-supplied input before incorporating it into PHP include() or require() statements. This design flaw enables attackers with low-level authentication to manipulate file path parameters and force the application to include arbitrary files from the local filesystem.

The vulnerability requires network access and some level of authentication (low privileges), but once these conditions are met, exploitation can lead to complete compromise of confidentiality, integrity, and availability of the affected system. The attack complexity is considered high, suggesting that specific conditions or configurations may be required for successful exploitation.

Root Cause

The root cause of this vulnerability lies in insufficient input validation within the Calafate theme's file handling mechanisms. When the theme processes user-controllable parameters that influence file path construction, it fails to implement proper sanitization to prevent path traversal sequences (such as ../) or to restrict file inclusion to a designated safe directory. This allows attackers to escape the intended file context and include arbitrary files from anywhere on the server's filesystem.

Attack Vector

The attack is conducted over the network against WordPress installations running the vulnerable Calafate theme. An attacker with low-level authentication (such as a subscriber or contributor role) can craft malicious requests containing manipulated file path parameters. By using directory traversal techniques, the attacker can navigate outside the intended directory structure to include sensitive files such as /etc/passwd, WordPress configuration files (wp-config.php), or application logs.

In more sophisticated attack scenarios, an attacker could chain this LFI vulnerability with log poisoning techniques—injecting malicious PHP code into log files and then including those logs to achieve remote code execution. Additionally, if the server configuration allows, attackers might attempt to include remote files, although the primary classification focuses on local file inclusion.

Detection Methods for CVE-2025-69342

Indicators of Compromise

• HTTP requests containing path traversal sequences (../, ..%2f, ....//) in theme-related parameters
• Access logs showing attempts to include sensitive system files like /etc/passwd or wp-config.php
• Unusual file access patterns from the web server process targeting configuration or log files
• Error logs indicating failed file inclusion attempts or PHP warnings related to include/require functions

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in request parameters
• Monitor web server access logs for suspicious requests targeting the Calafate theme with unusual file path parameters
• Deploy file integrity monitoring on sensitive configuration files to detect unauthorized access attempts
• Use SIEM correlation rules to identify patterns of LFI probing across multiple endpoints

Monitoring Recommendations

• Enable verbose PHP error logging and monitor for include/require-related warnings and errors
• Configure real-time alerting for access attempts to sensitive system files from web application contexts
• Monitor WordPress user activity logs for authenticated users making unusual theme-related requests
• Implement application-level logging to track file path parameters passed to include functions

How to Mitigate CVE-2025-69342

Immediate Actions Required

• Immediately deactivate and remove the Calafate theme if running version 1.7.7 or earlier
• Switch to a secure alternative WordPress theme until a patched version is available
• Review web server logs for evidence of exploitation attempts
• Audit WordPress user accounts and remove any unnecessary or suspicious accounts with authentication privileges

Patch Information

As of the last update on 2026-01-08, no official patch has been documented in the vulnerability database. Website administrators should monitor the Patchstack Vulnerability Database for updates regarding a security fix from VanKarWai. Until a patch is available, the recommended approach is to disable the vulnerable theme entirely.

Workarounds

• Disable the Calafate theme and switch to a secure alternative theme immediately
• Implement WAF rules to block requests containing path traversal sequences targeting theme parameters
• Restrict file system permissions to limit web server access to only necessary directories
• Use PHP open_basedir configuration to restrict file operations to specific directories
• Consider implementing additional authentication layers to limit access to WordPress administrative functions

# PHP configuration hardening example for open_basedir restriction
# Add to php.ini or .htaccess (Apache) to restrict file access
open_basedir = /var/www/html/wordpress:/tmp

# Apache mod_rewrite rules to block path traversal attempts
RewriteEngine On
RewriteCond %{QUERY_STRING} \.\./ [NC,OR]
RewriteCond %{QUERY_STRING} \.\.%2f [NC]
RewriteRule .* - [F,L]
