CVE-2026-22369: Ironfit Theme File Inclusion Vulnerability

CVE-2026-22369 Overview

CVE-2026-22369 is a Local File Inclusion (LFI) vulnerability affecting the AncoraThemes Ironfit WordPress theme. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include local files from the server. This flaw can lead to sensitive information disclosure, arbitrary file read, and potentially remote code execution if combined with other attack vectors.

Critical Impact

Remote attackers can exploit this vulnerability to read sensitive files from the WordPress server, potentially exposing configuration files, credentials, and other critical data without authentication.

Affected Products

• AncoraThemes Ironfit WordPress Theme version 1.5 and earlier
• WordPress installations using the Ironfit theme

Technical Details for CVE-2026-22369

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Ironfit WordPress theme fails to properly sanitize user-supplied input before passing it to PHP include or require functions. This allows an attacker to manipulate file path parameters to include arbitrary local files from the server's filesystem.

The attack can be executed remotely over the network, though successful exploitation requires navigating certain conditions. Once exploited, the impact is severe across confidentiality, integrity, and availability dimensions. An attacker could read sensitive configuration files such as wp-config.php, potentially gaining database credentials and authentication keys.

Root Cause

The vulnerability exists due to insufficient input validation and sanitization in the theme's file inclusion logic. The affected code accepts user-controlled input for file paths without properly restricting the allowed values or validating that the requested file resides within expected directories. This failure to implement a whitelist approach or proper path canonicalization enables path traversal sequences to escape intended directories.

Attack Vector

The vulnerability is exploitable via network requests to the WordPress site running the vulnerable Ironfit theme. An attacker can craft malicious requests containing path traversal sequences (such as ../) to navigate outside the intended directory structure and include arbitrary files from the server filesystem.

Typical exploitation involves manipulating URL parameters or POST data to inject path traversal payloads targeting sensitive files. For detailed technical analysis, refer to the Patchstack WordPress Vulnerability Database.

Detection Methods for CVE-2026-22369

Indicators of Compromise

• Web server access logs containing path traversal sequences (../, ..%2f, %2e%2e/) in requests to theme-related endpoints
• Unusual file access patterns in PHP error logs indicating attempts to read files outside web directories
• Requests targeting sensitive files like /etc/passwd, wp-config.php, or .htaccess through theme parameters
• Error messages revealing file system paths in server responses

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in request parameters
• Monitor PHP error logs for "failed to open stream" errors with unexpected file paths
• Deploy intrusion detection signatures for LFI attack patterns targeting WordPress themes
• Review web server logs for requests containing encoded traversal sequences or null bytes

Monitoring Recommendations

• Enable detailed access logging for WordPress theme requests and monitor for anomalous patterns
• Configure alerting for high-frequency requests to theme endpoints from single IP addresses
• Implement file integrity monitoring for critical WordPress configuration files
• Set up real-time alerting for WAF rule triggers related to path traversal attacks

How to Mitigate CVE-2026-22369

Immediate Actions Required

• Deactivate the Ironfit theme immediately if running version 1.5 or earlier
• Switch to a default WordPress theme (such as Twenty Twenty-Four) until a patched version is available
• Review server access logs for any signs of exploitation attempts
• Implement WAF rules to block path traversal attack patterns
• Restrict file system permissions to limit PHP's ability to read sensitive files

Patch Information

As of the last CVE update on 2026-02-24, no official patch from AncoraThemes has been referenced in the vulnerability databases. Organizations should monitor the Patchstack vulnerability database for updates on patches or vendor advisories. Contact the theme vendor directly to inquire about a security update timeline.

Workarounds

• Implement strict input validation via a security plugin that filters path traversal sequences in all request parameters
• Deploy ModSecurity or similar WAF with rules to block LFI attack patterns
• Use PHP open_basedir configuration to restrict PHP file access to the WordPress directory only
• Consider using a WordPress security plugin that provides virtual patching capabilities
• Apply principle of least privilege to web server file permissions to minimize exposure of sensitive files
