CVE-2026-22477: Felizia Theme Path Traversal Vulnerability

CVE-2026-22477 Overview

CVE-2026-22477 is a Local File Inclusion (LFI) vulnerability affecting the Felizia WordPress theme developed by AncoraThemes. 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 filesystem. This type of vulnerability can lead to sensitive information disclosure, configuration file exposure, and potentially remote code execution when combined with other attack vectors.

Critical Impact

Attackers can exploit this Local File Inclusion vulnerability to read sensitive server files, potentially exposing credentials, configuration data, and other confidential information that could be leveraged for further attacks.

Affected Products

• Felizia WordPress Theme version 1.3.4 and earlier
• AncoraThemes Felizia (all versions through 1.3.4)

Technical Details for CVE-2026-22477

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Felizia theme fails to properly sanitize user-supplied input before using it in PHP file inclusion operations. When a PHP application uses dynamic values in include(), require(), include_once(), or require_once() statements without adequate validation, attackers can manipulate the file path to include unintended files.

In WordPress theme contexts, such vulnerabilities commonly occur in template loading mechanisms, AJAX handlers, or shortcode implementations where file paths are constructed using user-controllable parameters. The lack of proper input validation and path canonicalization allows directory traversal sequences to escape the intended directory structure.

Root Cause

The root cause of this vulnerability lies in the improper handling of filename parameters within PHP include or require statements. The Felizia theme does not adequately validate, sanitize, or restrict the file paths that can be included, enabling attackers to traverse directory structures using sequences like ../ to access files outside the intended scope.

Attack Vector

Exploitation of this Local File Inclusion vulnerability typically involves manipulating URL parameters, POST data, or other user-controllable inputs that are passed to PHP file inclusion functions. An attacker can craft requests containing directory traversal sequences to read sensitive files such as /etc/passwd, wp-config.php, or other configuration files containing database credentials and authentication secrets.

The vulnerability can be exploited remotely by any user who can send HTTP requests to the affected WordPress installation. While the CWE classification mentions "Remote File Inclusion" in the vulnerability title, the actual impact assessment confirms this as a Local File Inclusion vulnerability, meaning attackers can include files already present on the target server rather than external files from attacker-controlled servers.

Detection Methods for CVE-2026-22477

Indicators of Compromise

• HTTP requests containing directory traversal sequences (../, ..%2f, %2e%2e/) targeting Felizia theme endpoints
• Unusual access patterns to theme files with file path parameters containing traversal attempts
• Web server logs showing attempts to access sensitive system files through theme URLs
• Failed or successful requests attempting to read /etc/passwd, wp-config.php, or similar sensitive files

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block directory traversal patterns in request parameters
• Monitor web server access logs for requests containing encoded or plain-text traversal sequences targeting the Felizia theme
• Implement file integrity monitoring on critical WordPress and system configuration files
• Configure intrusion detection systems to alert on Local File Inclusion attack signatures

Monitoring Recommendations

• Enable verbose logging for WordPress and web server to capture detailed request parameters
• Monitor for abnormal file access patterns, particularly reads of sensitive configuration files
• Set up alerts for requests containing ../ sequences or URL-encoded variants
• Review web application logs regularly for reconnaissance activity targeting theme endpoints

How to Mitigate CVE-2026-22477

Immediate Actions Required

• Update the Felizia theme to a patched version when available from AncoraThemes
• If no patch is available, consider temporarily deactivating the Felizia theme and switching to a secure alternative
• Implement WAF rules to block directory traversal attempts targeting the affected theme
• Review and restrict file permissions on sensitive server files to limit exposure

Patch Information

Users should check the Patchstack WordPress Vulnerability Database for the latest patch status and update information. Contact AncoraThemes directly for information about security updates for the Felizia theme. Always ensure WordPress core, themes, and plugins are kept up to date.

Workarounds

• Deploy a Web Application Firewall with rules blocking LFI attack patterns including ../ and encoded variants
• Use WordPress security plugins that provide virtual patching capabilities for known vulnerabilities
• Restrict access to the WordPress admin area and theme files using IP whitelisting where feasible
• Implement the principle of least privilege for file system permissions, ensuring the web server user cannot read unnecessary sensitive files

# Example Apache mod_rewrite rule to block directory traversal attempts
RewriteEngine On
RewriteCond %{QUERY_STRING} (\.\./|\.\.%2f) [NC,OR]
RewriteCond %{REQUEST_URI} (\.\./|\.\.%2f) [NC]
RewriteRule .* - [F,L]
