CVE-2025-22712: Typify WordPress Theme LFI Vulnerability

CVE-2025-22712 Overview

CVE-2025-22712 is a critical PHP Local File Inclusion (LFI) vulnerability affecting the QantumThemes Typify WordPress theme. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include arbitrary local files on the server. This type of vulnerability can lead to sensitive data disclosure, remote code execution through log poisoning, and complete server compromise.

Critical Impact

This vulnerability allows unauthenticated attackers to include arbitrary local files on the affected WordPress installation, potentially leading to disclosure of sensitive configuration files, credentials, and in some cases, remote code execution.

Affected Products

• QantumThemes Typify WordPress Theme versions through 3.0.2
• WordPress installations using the vulnerable Typify theme
• Web servers hosting affected WordPress sites

Technical Details for CVE-2025-22712

Vulnerability Analysis

This vulnerability is classified as CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Typify WordPress theme fails to properly validate and sanitize user-supplied input before using it in PHP include() or require() statements. This allows an attacker to manipulate the file path parameter to include arbitrary files from the local file system.

The attack can be executed remotely over the network without any authentication or user interaction required. Successful exploitation grants attackers the ability to read sensitive files such as wp-config.php (containing database credentials), system files like /etc/passwd, or other configuration files. When combined with techniques like log poisoning or PHP filter chains, this vulnerability can escalate to full remote code execution.

Root Cause

The root cause lies in insufficient input validation within the Typify theme's PHP code. User-controlled parameters are passed directly or with inadequate filtering to file inclusion functions. The theme does not implement proper path canonicalization, allowlisting, or traversal sequence filtering, enabling directory traversal attacks that break out of the intended directory scope.

Attack Vector

An attacker can exploit this vulnerability by crafting malicious HTTP requests containing path traversal sequences (such as ../) in parameters that are processed by the vulnerable include/require statements. The attack follows this general pattern:

1. Identify the vulnerable endpoint in the Typify theme
2. Craft a request with directory traversal sequences to escape the web root
3. Target sensitive files such as /etc/passwd or WordPress configuration files
4. Extract sensitive information or chain with other techniques for code execution

The vulnerability can be exploited through specially crafted URLs or POST parameters that reach the vulnerable code path. For detailed technical information, refer to the Patchstack WordPress Vulnerability Advisory.

Detection Methods for CVE-2025-22712

Indicators of Compromise

• Web server access logs containing path traversal sequences (../, ..%2f, %2e%2e/) targeting Typify theme files
• Requests attempting to access sensitive files like wp-config.php, /etc/passwd, or .htaccess
• Unusual file access patterns in PHP error logs referencing files outside the theme directory
• Failed or successful attempts to read system configuration files through web requests

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block path traversal patterns in requests targeting WordPress themes
• Implement file integrity monitoring on critical WordPress and system configuration files
• Configure intrusion detection systems (IDS) with signatures for LFI exploitation attempts
• Enable verbose PHP logging to capture include/require errors that may indicate exploitation attempts

Monitoring Recommendations

• Monitor web server access logs for requests containing encoded or plain-text directory traversal sequences
• Set up alerts for any access attempts to the Typify theme directory with suspicious parameters
• Review PHP error logs regularly for "failed to open stream" or "include(): Failed opening" errors
• Implement real-time log analysis for patterns matching known LFI exploitation techniques

How to Mitigate CVE-2025-22712

Immediate Actions Required

• Update the Typify WordPress theme to a patched version when available from QantumThemes
• If no patch is available, consider temporarily disabling or removing the Typify theme
• Implement WAF rules to block requests containing path traversal sequences
• Restrict file system permissions to limit readable files by the web server process
• Review and harden PHP configuration settings (open_basedir, allow_url_include)

Patch Information

As of the last update on 2026-01-08, users should check the Patchstack WordPress Vulnerability Advisory for the latest patch information from QantumThemes. Version 3.0.2 and all prior versions are confirmed vulnerable.

Workarounds

• Implement strict input validation at the web server or WAF level to reject requests with path traversal characters
• Configure PHP open_basedir directive to restrict file access to the WordPress directory only
• Disable the vulnerable theme and switch to an alternative theme until a patch is released
• Use .htaccess rules to block direct access to theme PHP files that process user input

# Apache .htaccess configuration to restrict theme file access
<Directory /var/www/html/wp-content/themes/typify>
    <FilesMatch "\.php$">
        # Allow only internal WordPress includes
        Order Deny,Allow
        Deny from all
        Allow from 127.0.0.1
    </FilesMatch>
</Directory>

# PHP open_basedir restriction in php.ini or vhost config
# open_basedir = /var/www/html/:/tmp/
