CVE-2026-39547: Getaway Path Traversal Vulnerability

CVE-2026-39547 Overview

CVE-2026-39547 is an unauthenticated Local File Inclusion (LFI) vulnerability affecting the WordPress Getaway theme in versions prior to 1.8. The flaw allows remote attackers to include arbitrary local files through unsanitized input passed to a file inclusion routine. Successful exploitation can disclose sensitive configuration files, leak credentials, or enable code execution when chained with file upload primitives. The vulnerability is tracked under CWE-98: Improper Control of Filename for Include/Require Statement in PHP Program. No authentication is required, expanding the exposure to any internet-reachable WordPress site running the affected theme.

Critical Impact
Unauthenticated attackers can read arbitrary local files on the server and potentially achieve remote code execution by including attacker-controlled content.

Affected Products

WordPress Getaway theme versions prior to 1.8
WordPress sites with the Getaway theme installed and active
Hosting environments serving the vulnerable theme files

Technical Details for CVE-2026-39547

Vulnerability Analysis

The Getaway theme accepts user-controlled input that flows into a PHP include, require, include_once, or require_once statement without proper validation or sanitization. Attackers send crafted HTTP requests that reference local filesystem paths, causing the PHP interpreter to load and execute the targeted file in the application context. Because the affected endpoint does not enforce authentication, anyone able to reach the WordPress instance can trigger the inclusion. The attack vector is network-based and requires no user interaction, though the CVSS metrics indicate higher attack complexity, suggesting specific conditions must be met for reliable exploitation.

Root Cause

The root cause is improper neutralization of filename input used in a PHP file inclusion statement, classified under CWE-98. The theme trusts request parameters as filesystem paths and fails to enforce an allowlist, canonicalize paths, or reject directory traversal sequences such as ../. This allows an attacker to escape the intended template directory and reference arbitrary files readable by the web server process.

Attack Vector

An attacker issues an unauthenticated HTTP request to a vulnerable Getaway theme endpoint, supplying a path parameter that points outside the theme directory. Typical targets include wp-config.php for database credentials and secret keys, /etc/passwd on Linux hosts, or log files for poisoning attacks. When combined with log poisoning or an uploadable PHP payload, the LFI can be escalated to remote code execution under the web server account. See the Patchstack WordPress Vulnerability Report for additional technical context.

Detection Methods for CVE-2026-39547

Indicators of Compromise

HTTP requests to Getaway theme files containing path traversal sequences such as ../, ..%2f, or encoded null bytes
Web server access log entries referencing wp-config.php, /etc/passwd, or php://filter wrappers in query parameters
Unexpected outbound connections originating from the PHP-FPM or web server process following suspicious inclusion requests
New or modified PHP files in the WordPress uploads directory following log access patterns

Detection Strategies

Inspect web server and WAF logs for requests targeting /wp-content/themes/getaway/ with parameters containing filesystem paths or PHP stream wrappers
Apply YARA or regex rules that flag file=, page=, or similar query parameters carrying traversal payloads
Correlate file read events on sensitive paths such as wp-config.php with the originating PHP process and parent HTTP request

Monitoring Recommendations

Enable WordPress audit logging to capture theme file access and configuration reads
Monitor for anomalous PHP process behavior, including spawning of shell utilities such as sh, bash, or curl
Alert on egress traffic from the web tier to non-business destinations, which can indicate post-exploitation activity

How to Mitigate CVE-2026-39547

Immediate Actions Required

Update the Getaway theme to version 1.8 or later on all affected WordPress installations
Audit wp-config.php for credential exposure and rotate database passwords, authentication keys, and salts if compromise is suspected
Restrict access to the WordPress instance behind a WAF or reverse proxy with traversal-blocking rules until patching is complete

Patch Information

The vendor advisory referenced through the Patchstack WordPress Vulnerability Report identifies version 1.8 as the fixed release. Administrators should apply the update through the WordPress theme management interface or replace the theme files manually from a trusted source.

Workarounds

Deactivate the Getaway theme and switch to an unaffected theme until the patch is applied
Deploy WAF rules that block traversal sequences and PHP stream wrappers in query strings targeting theme paths
Configure PHP open_basedir to restrict file inclusion to the WordPress installation directory
Set allow_url_include = Off and allow_url_fopen = Off in php.ini to prevent remote inclusion escalation

bash

# Configuration example: harden PHP against file inclusion abuse
# /etc/php/php.ini
allow_url_include = Off
allow_url_fopen = Off
open_basedir = "/var/www/html:/tmp"

# Example WAF rule (ModSecurity) blocking traversal in theme requests
SecRule REQUEST_URI "@contains /wp-content/themes/getaway/" \
  "chain,id:1039547,phase:2,deny,status:403,msg:'Getaway LFI attempt'"
  SecRule ARGS "@rx (\.\./|\.\.\\|php://|file://|data://)" "t:none,t:urlDecodeUni"
