CVE-2026-22514: Unica WordPress Theme LFI Vulnerability

CVE-2026-22514 Overview

CVE-2026-22514 is a Local File Inclusion (LFI) vulnerability in the AncoraThemes Unica 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 weakness is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program).

Critical Impact

Successful exploitation could allow unauthenticated attackers to read sensitive files, potentially leading to information disclosure, configuration exposure, or in some cases, remote code execution when combined with other techniques such as log poisoning.

Affected Products

• AncoraThemes Unica WordPress Theme versions up to and including 1.4.1

Technical Details for CVE-2026-22514

Vulnerability Analysis

This Local File Inclusion vulnerability exists in the AncoraThemes Unica WordPress theme due to insufficient validation of user-supplied input that is passed to PHP's include() or require() functions. When user input is not properly sanitized before being used to construct file paths, attackers can manipulate the input to traverse directories and include arbitrary files from the local filesystem.

The vulnerability requires a network-based attack and involves some complexity in exploitation, but it does not require authentication or user interaction. If successfully exploited, an attacker could potentially read sensitive configuration files such as wp-config.php, access database credentials, or view other sensitive server-side files.

Root Cause

The root cause of this vulnerability is the failure to properly validate and sanitize user-controlled input before using it in file inclusion operations. The Unica theme likely accepts a parameter that is intended to specify a template or component file to include, but does not adequately restrict the input to prevent directory traversal sequences (such as ../) or absolute paths that could reference files outside the intended directory.

Attack Vector

The attack vector is network-based, meaning attackers can exploit this vulnerability remotely without requiring local access to the target system. The exploitation involves manipulating HTTP request parameters to inject path traversal sequences into file inclusion operations.

A typical attack scenario involves an attacker sending crafted requests containing directory traversal patterns to access files outside the web root, such as /etc/passwd on Linux systems or WordPress configuration files containing database credentials. While the primary classification is Local File Inclusion, in certain configurations where remote file wrappers are enabled, this could potentially escalate to Remote File Inclusion.

The vulnerability mechanism involves PHP's file inclusion functions accepting user-controllable input without proper validation. An attacker would craft a request containing path traversal sequences to reference sensitive files on the server filesystem.

Detection Methods for CVE-2026-22514

Indicators of Compromise

• HTTP requests containing path traversal sequences such as ../, ..%2f, or ..%5c targeting WordPress theme endpoints
• Unusual access patterns to WordPress theme files within the /wp-content/themes/unica/ directory
• Web server logs showing requests attempting to access sensitive files like /etc/passwd or wp-config.php
• Error messages in application logs indicating failed file inclusion attempts

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in HTTP requests
• Monitor WordPress access logs for suspicious requests targeting the Unica theme directory
• Configure file integrity monitoring on sensitive configuration files to detect unauthorized access
• Deploy intrusion detection system (IDS) signatures for PHP LFI attack patterns

Monitoring Recommendations

• Enable verbose logging on the web server to capture full request URIs and parameters
• Set up alerts for anomalous access patterns to WordPress theme files
• Monitor for new or modified files in the WordPress installation that could indicate post-exploitation activity
• Implement real-time log analysis to detect LFI attack attempts as they occur

How to Mitigate CVE-2026-22514

Immediate Actions Required

• Update the AncoraThemes Unica theme to a patched version newer than 1.4.1 when available
• If no patch is available, consider temporarily disabling or replacing the vulnerable theme
• Implement WAF rules to block path traversal attempts targeting WordPress endpoints
• Restrict file system permissions to limit the impact of potential file inclusion attacks
• Disable unnecessary PHP wrappers such as allow_url_include in php.ini

Patch Information

No official patch information has been published as of the last NVD update on 2026-03-26. Website administrators should monitor the Patchstack WordPress Theme Advisory for updates regarding an official fix from AncoraThemes.

Workarounds

• Switch to an alternative WordPress theme until a patched version of Unica is available
• Implement server-level restrictions using .htaccess or nginx configuration to block suspicious requests
• Use a security plugin that provides virtual patching capabilities for known vulnerabilities
• Apply the principle of least privilege to the web server user to minimize the impact of successful exploitation

# Configuration example - Apache .htaccess rule to block path traversal attempts
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{QUERY_STRING} (\.\./|\.\.) [NC,OR]
    RewriteCond %{REQUEST_URI} (\.\./|\.\.) [NC]
    RewriteRule .* - [F,L]
</IfModule>
