CVE-2026-22330: Right Way Path Traversal Vulnerability

CVE-2026-22330 Overview

CVE-2026-22330 is an unauthenticated Local File Inclusion (LFI) vulnerability affecting the Right Way WordPress theme in versions 4.0 and earlier. The flaw is classified under [CWE-98] (Improper Control of Filename for Include/Require Statement in PHP Program). An unauthenticated remote attacker can manipulate file path parameters to force the application to include arbitrary local files. Successful exploitation can expose sensitive configuration data, credentials, and, depending on the server configuration, lead to remote code execution through PHP file inclusion.

Critical Impact
Unauthenticated attackers can read arbitrary files on the host and potentially execute PHP code by including attacker-controlled content, compromising confidentiality, integrity, and availability of WordPress sites running the Right Way theme.

Affected Products

Right Way WordPress theme version 4.0
Right Way WordPress theme versions prior to 4.0
WordPress installations bundling the Right Way theme

Technical Details for CVE-2026-22330

Vulnerability Analysis

The vulnerability is an Local File Inclusion flaw in the Right Way WordPress theme. The theme passes user-supplied input into a PHP include, require, or equivalent file-loading construct without sufficient validation. Because authentication is not required, any anonymous HTTP client can target the affected endpoint over the network.

LFI bugs of this class allow attackers to traverse the filesystem and load files such as wp-config.php, which contains database credentials and WordPress secret keys. If the theme accepts remote paths or includes attacker-uploaded content, the bug can escalate to arbitrary PHP code execution. The Patchstack advisory tracks this issue against Right Way 4.0 and earlier releases.

Root Cause

The root cause is improper control of a filename parameter used in a PHP include statement, mapped to [CWE-98]. The theme fails to validate or sanitize a request parameter before passing it to a dynamic include directive. There is no allowlist of permitted templates, no path canonicalization, and no restriction on traversal sequences such as ../. As a result, the include resolves to attacker-controlled file paths.

Attack Vector

An attacker sends a crafted HTTP request to a vulnerable theme endpoint, supplying a manipulated parameter that points to a target file path on the server. The PHP runtime evaluates and includes that file. Typical targets include wp-config.php, log files containing injected PHP payloads, and uploaded media. Exploitation requires no credentials or user interaction, but the attack complexity is elevated because reliable exploitation depends on server configuration, file paths, and PHP settings such as allow_url_include. Refer to the Patchstack WordPress Vulnerability Report for additional technical context.

Detection Methods for CVE-2026-22330

Indicators of Compromise

HTTP requests to Right Way theme paths containing traversal sequences such as ../, ..%2f, or encoded null bytes
Web server access logs showing parameters referencing wp-config.php, /etc/passwd, or /proc/self/environ
PHP error logs indicating include or require failures originating from theme files under wp-content/themes/rightway/
Outbound connections from the PHP worker to attacker-controlled hosts following an inclusion request

Detection Strategies

Inspect web server and WAF logs for query parameters containing path traversal patterns targeting theme endpoints
Alert on unusual reads of sensitive WordPress files, including wp-config.php and .htaccess, by the PHP process
Correlate HTTP request anomalies with file system access events on hosts running the Right Way theme
Monitor PHP execution telemetry for include or require calls resolving outside the theme directory

Monitoring Recommendations

Enable verbose access logging on WordPress front-end servers and forward logs to a centralized analytics platform
Track installations of the Right Way theme across the estate and flag versions at or below 4.0
Establish baselines for theme endpoint traffic and alert on parameter values containing filesystem path syntax
Review outbound network connections from PHP-FPM or Apache worker processes to detect post-exploitation activity

How to Mitigate CVE-2026-22330

Immediate Actions Required

Inventory all WordPress sites and identify any using the Right Way theme version 4.0 or earlier
Take affected sites offline or place them behind a restrictive web application firewall until remediation is complete
Rotate WordPress secret keys, database credentials, and any API tokens stored in wp-config.php if exposure is suspected
Review web server access logs for prior exploitation attempts targeting theme endpoints

Patch Information

No vendor patch is referenced in the available advisory data for CVE-2026-22330. Site operators should consult the Patchstack WordPress Vulnerability Report for current vendor status. If no fixed version is available, replace the Right Way theme with a maintained alternative.

Workarounds

Deploy WAF rules that block traversal sequences and absolute paths in query parameters targeting theme files
Disable the Right Way theme and switch to a supported theme until a fix is published
Set the PHP directive allow_url_include=Off and restrict open_basedir to the WordPress document root
Apply least-privilege filesystem permissions so the PHP process cannot read sensitive system files

bash

# Configuration example: restrict PHP file inclusion scope
# /etc/php/8.x/fpm/conf.d/99-hardening.ini
allow_url_include = Off
allow_url_fopen = Off
open_basedir = "/var/www/wordpress:/tmp"
disable_functions = "exec,passthru,shell_exec,system,proc_open,popen"
