CVE-2025-69163: WineShop Path Traversal Vulnerability

CVE-2025-69163 Overview

CVE-2025-69163 is an unauthenticated Local File Inclusion (LFI) vulnerability affecting the WineShop WordPress theme in versions 3.17 and earlier. The flaw is tracked under CWE-98, Improper Control of Filename for Include/Require Statement in PHP Program. Remote attackers can include arbitrary local files into PHP execution flow without authentication. Successful exploitation can disclose sensitive configuration data, expose credentials, and in certain hosting configurations lead to code execution.

Critical Impact
Unauthenticated attackers can read or include arbitrary local files on servers running vulnerable WineShop theme installations, putting confidentiality, integrity, and availability at risk.

Affected Products

WineShop WordPress theme versions <= 3.17
WordPress sites using the WineShop theme as the active theme
Hosting environments where the vulnerable theme files are reachable via HTTP

Technical Details for CVE-2025-69163

Vulnerability Analysis

The WineShop theme contains a PHP file inclusion path that incorporates user-controlled input into an include, require, or equivalent statement. Because the input is neither validated against an allowlist nor sanitized for traversal sequences, attackers can supply crafted values that resolve to arbitrary paths on the local file system. The issue falls squarely within [CWE-98], Improper Control of Filename for Include/Require Statement in PHP Program.

Exploitation requires no authentication and no user interaction. An attacker only needs network access to the affected WordPress site. According to Patchstack, the vulnerability impacts all WineShop versions through 3.17.

Root Cause

The root cause is unsafe handling of a request parameter that flows into a PHP file inclusion function. The vulnerable code path trusts attacker-controlled input to determine which file the PHP interpreter loads. Without a strict allowlist of permitted templates or normalization of traversal sequences such as ../, the inclusion target can be redirected to sensitive files outside the theme directory.

Attack Vector

The attack vector is network-based. An attacker sends an HTTP request to the vulnerable theme endpoint with a manipulated parameter pointing at a target file path. The PHP runtime then includes the chosen file in the response context, executing any PHP it contains or returning its contents. Common targets include wp-config.php, server log files used for log poisoning, and uploaded files staged for execution. See the Patchstack WordPress Vulnerability Report for additional context.

Detection Methods for CVE-2025-69163

Indicators of Compromise

HTTP requests to WineShop theme files containing path traversal patterns such as ../, ..%2f, or encoded null bytes in query parameters
Web server access logs showing requests for sensitive paths like wp-config.php, /etc/passwd, or PHP session files via theme parameters
Unexpected PHP errors referencing include(), require(), or failed to open stream originating from WineShop theme files
New or modified PHP files in wp-content/uploads/ following inclusion-style requests, indicating possible log poisoning or upload-to-include chains

Detection Strategies

Inspect WordPress access logs for query strings that reference file paths, traversal sequences, or php:// and data:// wrappers targeting WineShop theme endpoints
Deploy web application firewall rules that block requests containing directory traversal patterns aimed at theme PHP files
Hunt for PHP processes spawning shell utilities or outbound connections from the web server user account after suspicious theme requests
Correlate WordPress audit logs with file integrity monitoring to spot reads of wp-config.php and theme-controlled inclusions

Monitoring Recommendations

Enable verbose access logging on the WordPress web server and forward logs to a central analytics platform for query-string inspection
Alert on 200-status responses to theme URLs that contain encoded traversal sequences or remote URL wrappers
Monitor PHP error logs for include/require warnings citing theme files, which often surface failed exploitation attempts
Track filesystem reads of wp-config.php and other secrets by the web server process using endpoint behavioral monitoring

How to Mitigate CVE-2025-69163

Immediate Actions Required

Identify all WordPress sites running the WineShop theme and confirm the installed version against the vulnerable range <= 3.17
Disable or switch away from the WineShop theme on any site that cannot immediately apply a vendor-supplied fix
Rotate WordPress secrets, database credentials, and API keys exposed in wp-config.php if exploitation is suspected
Place a web application firewall in blocking mode in front of affected WordPress sites to filter traversal patterns

Patch Information

At the time of publication, the Patchstack WordPress Vulnerability Report lists all WineShop versions through 3.17 as vulnerable. Administrators should consult the Patchstack advisory and the theme vendor for the latest fixed release, then update through the WordPress dashboard or by replacing the theme directory with a patched copy.

Workarounds

Restrict access to the WineShop theme directory via web server rules until a patched version is deployed
Configure PHP with open_basedir to confine inclusion paths to the WordPress installation directory
Disable PHP stream wrappers such as allow_url_include and allow_url_fopen to limit remote file inclusion escalation
Apply virtual patching at the WAF layer to block requests carrying ../, php://filter, or data:// payloads to theme endpoints

bash

# Configuration example: harden PHP and Apache against LFI exploitation
# php.ini
allow_url_include = Off
allow_url_fopen = Off
open_basedir = "/var/www/html:/tmp"

# Apache .htaccess in wp-content/themes/wineshop/
<FilesMatch "\.php$">
    Require all denied
</FilesMatch>
