CVE-2025-53446: Axiomthemes Beautique LFI Vulnerability

CVE-2025-53446 Overview

CVE-2025-53446 is a Local File Inclusion (LFI) vulnerability affecting the Axiomthemes Beautique 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's filesystem. This type of vulnerability can lead to sensitive information disclosure, configuration file exposure, and potentially escalate to remote code execution when combined with other attack techniques.

Critical Impact

Unauthenticated attackers can exploit this vulnerability over the network to read sensitive files, potentially exposing database credentials, WordPress configuration files, and other critical system data. In certain scenarios, this could lead to complete site compromise.

Affected Products

• Axiomthemes Beautique WordPress Theme versions up to and including 1.5
• WordPress installations running vulnerable Beautique theme versions
• Websites using Beautique theme without updated security patches

Technical Details for CVE-2025-53446

Vulnerability Analysis

This vulnerability is classified as CWE-98: Improper Control of Filename for Include/Require Statement in PHP Program. The Beautique WordPress theme fails to properly sanitize user-supplied input before using it in PHP file inclusion operations. An attacker can manipulate file path parameters to traverse directories and include arbitrary local files from the server.

The attack can be executed remotely without authentication, though it requires some complexity in crafting the malicious request. Successful exploitation can result in high impact to confidentiality, integrity, and availability of the affected system.

Root Cause

The root cause lies in insufficient input validation within the Beautique theme's PHP codebase. When processing user-supplied parameters that determine which files to include, the application fails to implement proper path validation, sanitization, or allowlist filtering. This allows directory traversal sequences (such as ../) to escape the intended directory scope and access files elsewhere on the filesystem.

Attack Vector

The vulnerability is exploitable over the network without requiring authentication. An attacker can craft malicious HTTP requests containing manipulated file path parameters targeting the vulnerable PHP include functionality. By using directory traversal techniques, the attacker can navigate outside the theme directory to access sensitive files such as:

• WordPress configuration files (wp-config.php) containing database credentials
• System files like /etc/passwd on Linux servers
• Log files that may contain sensitive information
• Other PHP files that could lead to code execution when combined with log poisoning techniques

The attack requires some complexity to successfully exploit, as the attacker needs to understand the server's file structure and craft appropriate traversal paths. For detailed technical information, see the Patchstack WordPress Vulnerability Advisory.

Detection Methods for CVE-2025-53446

Indicators of Compromise

• Web server access logs showing requests with directory traversal sequences (../, ..%2f, etc.) targeting theme endpoints
• Requests attempting to access sensitive files such as wp-config.php, /etc/passwd, or system log files
• Unusual file read operations originating from the web server process
• Error logs indicating failed file inclusion attempts outside normal theme directories

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block directory traversal patterns in HTTP requests
• Monitor access logs for suspicious file path manipulation attempts targeting the Beautique theme
• Deploy file integrity monitoring to detect unauthorized access to sensitive configuration files
• Utilize SentinelOne Singularity platform to detect and prevent exploitation attempts through behavioral analysis

Monitoring Recommendations

• Enable detailed access logging on web servers to capture full request URIs and parameters
• Configure alerts for file access attempts outside normal WordPress directories by the web server process
• Monitor for unusual patterns of file read operations that could indicate reconnaissance or exploitation
• Implement real-time log analysis to identify directory traversal attack patterns

How to Mitigate CVE-2025-53446

Immediate Actions Required

• Update the Axiomthemes Beautique theme to a patched version as soon as one becomes available
• Implement web application firewall rules to block directory traversal attempts
• Review web server access logs for signs of exploitation attempts
• Consider temporarily disabling the theme if a patch is not yet available and the site is critical

Patch Information

Organizations using the Axiomthemes Beautique WordPress theme should monitor the vendor's official channels and the Patchstack WordPress Vulnerability Advisory for patch availability. All installations running Beautique theme version 1.5 or earlier should be considered vulnerable and should be updated immediately once a security patch is released.

Workarounds

• Deploy a web application firewall (WAF) with rules configured to block path traversal sequences in request parameters
• Implement server-level restrictions using open_basedir PHP directive to limit file access to the WordPress directory
• Use file permission hardening to restrict read access to sensitive files from the web server process
• Consider switching to an alternative WordPress theme until an official patch is available
• Implement network-level access controls to restrict access to the WordPress admin and theme endpoints

# Example PHP configuration hardening in php.ini or .htaccess
# Restrict PHP file operations to WordPress directory
php_value open_basedir /var/www/html/wordpress/

# Example Apache mod_rewrite rules to block traversal attempts
# Add to .htaccess in WordPress root
RewriteEngine On
RewriteCond %{QUERY_STRING} (\.\./|\.\.) [NC]
RewriteRule .* - [F,L]
