CVE-2025-58946: Axiomthemes Vocal LFI Vulnerability

CVE-2025-58946 Overview

CVE-2025-58946 is a Local File Inclusion (LFI) vulnerability affecting the Axiomthemes Vocal WordPress theme. The vulnerability stems from improper control of filename parameters in PHP include/require statements, allowing attackers to include arbitrary local files on the server. This vulnerability class (CWE-98) can lead to sensitive information disclosure, arbitrary code execution, and full system compromise depending on the files accessible on the target system.

Critical Impact

Successful exploitation allows unauthenticated attackers to read sensitive configuration files, access database credentials, or achieve remote code execution through log poisoning or other techniques.

Affected Products

• Axiomthemes Vocal WordPress Theme versions up to and including 1.12
• WordPress installations running vulnerable Vocal theme versions

Technical Details for CVE-2025-58946

Vulnerability Analysis

The Vocal WordPress theme by Axiomthemes contains an Improper Control of Filename for Include/Require Statement vulnerability. This flaw allows attackers to manipulate file path parameters passed to PHP include or require functions, enabling inclusion of arbitrary local files from the server filesystem.

The vulnerability requires network access and can be exploited without authentication. While the attack complexity is high due to the specific conditions required for successful exploitation, the potential impact is severe—affecting confidentiality, integrity, and availability of the target system.

Root Cause

The root cause lies in insufficient input validation and sanitization of user-controlled parameters that are subsequently used in PHP file inclusion operations. The theme fails to properly restrict file paths, allowing path traversal sequences (such as ../) or absolute paths to be processed by include/require statements.

Attack Vector

The attack is conducted over the network and targets WordPress sites running the vulnerable Vocal theme. An attacker can craft malicious requests containing manipulated file path parameters. When processed by the theme's vulnerable code path, these parameters allow inclusion of local files such as /etc/passwd, WordPress configuration files (wp-config.php), or potentially log files that could be leveraged for code execution through log poisoning techniques.

The vulnerability manifests in file inclusion operations where user input is not properly sanitized before being passed to PHP's include or require functions. Attackers can leverage path traversal techniques to navigate the filesystem and include sensitive files. For detailed technical analysis, see the Patchstack WordPress Vulnerability Report.

Detection Methods for CVE-2025-58946

Indicators of Compromise

• Suspicious HTTP requests containing path traversal sequences (../, ..%2f, %2e%2e/) targeting theme endpoints
• Access log entries showing requests with unusual file path parameters (e.g., /etc/passwd, wp-config.php)
• Web server errors indicating failed file inclusion attempts
• Unexpected access patterns to theme-related URLs with manipulated parameters

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block path traversal patterns in request parameters
• Implement log monitoring for requests containing suspicious path manipulation sequences targeting WordPress theme endpoints
• Use endpoint detection tools to identify file access anomalies on WordPress installations
• Configure intrusion detection systems to alert on LFI attack signatures

Monitoring Recommendations

• Monitor WordPress access logs for unusual requests to Vocal theme files with path traversal indicators
• Enable PHP error logging to capture failed file inclusion attempts
• Implement file integrity monitoring on sensitive configuration files
• Review server access logs regularly for reconnaissance or exploitation attempts

How to Mitigate CVE-2025-58946

Immediate Actions Required

• Update the Axiomthemes Vocal theme to the latest patched version immediately
• If an update is unavailable, consider temporarily disabling or removing the Vocal theme
• Review WordPress installation for signs of compromise before and after remediation
• Implement WAF rules to block LFI attack patterns as an additional defense layer

Patch Information

Organizations should check the Patchstack WordPress Vulnerability Report for the latest patch information and update guidance from the vendor. Ensure you are running a version of the Vocal theme newer than 1.12.

Workarounds

• Temporarily disable or remove the Axiomthemes Vocal theme until a patch is applied
• Implement strict WAF rules to filter path traversal sequences in all request parameters
• Restrict PHP's open_basedir directive to limit file access scope
• Apply least privilege principles to WordPress file permissions

# Example: Restrict PHP open_basedir in Apache configuration
php_admin_value open_basedir "/var/www/html/:/tmp/"

# Example: Block path traversal in .htaccess
RewriteEngine On
RewriteCond %{QUERY_STRING} (\.\./|\.\.%2f) [NC,OR]
RewriteCond %{QUERY_STRING} (etc/passwd) [NC]
RewriteRule .* - [F,L]
