CVE-2025-32289: Yozi WordPress Theme LFI Vulnerability

CVE-2025-32289 Overview

CVE-2025-32289 is a Local File Inclusion (LFI) vulnerability affecting the ApusTheme Yozi WordPress theme. 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. This flaw can lead to unauthorized access to sensitive configuration files, source code disclosure, and potentially remote code execution when combined with other attack vectors.

Critical Impact

Unauthenticated attackers may exploit this LFI vulnerability to read sensitive server files, access WordPress configuration credentials, or escalate to remote code execution through log poisoning or PHP wrapper techniques.

Affected Products

• ApusTheme Yozi WordPress Theme versions up to and including 2.0.63
• WordPress installations utilizing the vulnerable Yozi theme

Technical Details for CVE-2025-32289

Vulnerability Analysis

The vulnerability exists due to insufficient input validation on user-controllable parameters that are subsequently used in PHP include(), require(), include_once(), or require_once() statements within the Yozi WordPress theme. Without proper sanitization, attackers can manipulate file paths to traverse directories and include arbitrary files from the local filesystem.

Local File Inclusion vulnerabilities in WordPress themes are particularly dangerous because they may allow attackers to access the wp-config.php file containing database credentials, read other plugin source code for further vulnerabilities, or leverage PHP wrappers like php://filter to extract base64-encoded source code. In some scenarios, attackers can escalate LFI to Remote Code Execution by poisoning log files or combining the attack with file upload functionality.

Root Cause

The root cause of CVE-2025-32289 is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Yozi theme fails to properly validate and sanitize user-supplied input before using it in dynamic file inclusion operations. The code likely uses unsanitized $_GET, $_POST, or $_REQUEST parameters directly in file path construction without implementing allowlist validation, path canonicalization, or directory restriction controls.

Attack Vector

The attack is network-accessible and does not require authentication, though it involves high complexity due to the need for specific conditions to be met for successful exploitation. Attackers craft malicious HTTP requests containing directory traversal sequences (such as ../) or PHP wrapper protocols to manipulate the file inclusion path. The attack targets the web application layer through standard HTTP requests to WordPress endpoints where the vulnerable theme code processes user input.

Exploitation typically involves identifying the vulnerable parameter, then crafting requests that traverse out of the expected directory structure to access sensitive files like /etc/passwd, wp-config.php, or other configuration files. More advanced exploitation may involve using PHP stream wrappers to read source code or combining the LFI with log poisoning techniques for code execution.

Detection Methods for CVE-2025-32289

Indicators of Compromise

• HTTP request logs containing directory traversal patterns such as ../, ..%2f, or ....// in GET/POST parameters
• Requests attempting to access sensitive files like wp-config.php, /etc/passwd, or proc/self/environ
• Unusual PHP wrapper usage in requests including php://filter, php://input, or data:// schemes
• Error logs showing file inclusion failures or warnings about non-existent paths outside the theme directory

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block directory traversal patterns and PHP wrapper attempts
• Enable verbose PHP error logging and monitor for inclusion-related warnings or errors
• Implement file integrity monitoring on WordPress core files and theme directories to detect unauthorized access attempts
• Review web server access logs for requests containing encoded traversal sequences or suspicious file paths targeting the Yozi theme

Monitoring Recommendations

• Configure SIEM alerts for patterns matching LFI exploitation attempts targeting WordPress installations
• Monitor for unusual file access patterns on sensitive configuration files through host-based intrusion detection
• Track WordPress theme file modifications and access times to identify potential compromise indicators
• Implement real-time log analysis for HTTP requests containing path traversal signatures or PHP wrapper protocols

How to Mitigate CVE-2025-32289

Immediate Actions Required

• Update the ApusTheme Yozi theme to the latest patched version if a security update is available from the vendor
• If no patch is available, consider temporarily deactivating the Yozi theme and switching to a secure alternative
• Implement WAF rules to block requests containing directory traversal sequences and PHP wrapper protocols
• Restrict PHP's open_basedir directive to limit file inclusion to the WordPress installation directory
• Review server access logs for evidence of prior exploitation attempts

Patch Information

Organizations should monitor the Patchstack Yozi Vulnerability Advisory for official patch availability and update instructions from ApusTheme. Apply the security update immediately once released and verify the patch addresses the file inclusion vulnerability.

Workarounds

• Configure open_basedir in PHP to restrict file access to the WordPress directory and prevent traversal to system files
• Implement ModSecurity or similar WAF rules to detect and block LFI attack patterns at the network edge
• Use a security plugin like Wordfence or Sucuri to add application-layer protection against file inclusion attacks
• If the vulnerable functionality is identified, consider manually patching the affected files by implementing input validation and allowlist-based file inclusion

# PHP configuration hardening example
# Add to php.ini or .htaccess to restrict file access

# Restrict PHP file operations to WordPress directory
php_admin_value open_basedir /var/www/html/wordpress/

# Disable dangerous PHP wrappers
php_admin_flag allow_url_include Off
php_admin_flag allow_url_fopen Off
