CVE-2025-39452: WPCafe Path Traversal Vulnerability

CVE-2025-39452 Overview

CVE-2025-39452 is a PHP Local File Inclusion (LFI) vulnerability in the Arraytics WPCafe WordPress plugin (wp-cafe). The flaw stems from improper control of filenames used in PHP include or require statements, classified under [CWE-98]. Authenticated attackers with low privileges can manipulate file path parameters to include arbitrary local PHP files on the server. The vulnerability affects all WPCafe versions from n/a through 2.2.32. Successful exploitation can lead to disclosure of sensitive configuration data, execution of attacker-controlled PHP files already present on the server, and full compromise of the WordPress site.

Critical Impact
Authenticated attackers can include arbitrary local PHP files through the WPCafe plugin, exposing site secrets and enabling remote code execution paths.

Affected Products

Arraytics WPCafe (wp-cafe) WordPress plugin
All versions up to and including 2.2.32
WordPress sites with the WPCafe plugin installed and activated

Technical Details for CVE-2025-39452

Vulnerability Analysis

The WPCafe plugin passes user-supplied input into a PHP include or require statement without adequate validation or sanitization. This pattern matches the classic PHP File Inclusion weakness described in [CWE-98]. An attacker with a low-privilege authenticated session can supply a crafted path value that resolves to a local file outside the intended directory. The PHP interpreter then loads and executes that file in the context of the WordPress process. Attack complexity is elevated because the request requires specific conditions to succeed, but no user interaction is needed once the attacker holds valid credentials.

Root Cause

The root cause is the absence of an allowlist for include targets. The plugin treats a request parameter as a trusted path component when building the argument to a dynamic include. Path normalization, extension checks, and base-directory enforcement are missing, so traversal sequences such as ../ reach the file system layer intact.

Attack Vector

The attack is delivered over the network against the WordPress HTTP interface. The attacker authenticates with any account that can reach the vulnerable endpoint, then submits a request containing a manipulated file path. The vulnerable handler concatenates the value into a PHP inclusion call, causing the server to parse and execute the referenced file. Refer to the Patchstack CVE Analysis for endpoint-level details.

Detection Methods for CVE-2025-39452

Indicators of Compromise

HTTP requests to WPCafe plugin endpoints containing traversal sequences such as ../, ..%2f, or absolute paths like /etc/passwd and wp-config.php
Unexpected PHP execution originating from the wp-content/plugins/wp-cafe/ directory tree
Web server access logs showing authenticated POST or GET requests with file path parameters referencing files outside the plugin directory
New or modified PHP files in WordPress upload directories that are subsequently referenced by plugin requests

Detection Strategies

Inspect WordPress and web server logs for parameter values containing path traversal characters routed to wp-cafe handlers
Apply web application firewall rules that flag LFI patterns in query strings and POST bodies targeting /wp-admin/admin-ajax.php actions registered by WPCafe
Correlate authenticated low-privilege sessions with abnormal file-read behavior from the php-fpm or web server process

Monitoring Recommendations

Alert on PHP process reads of sensitive files such as wp-config.php, .env, and SSH key paths when initiated by the web server user
Monitor for outbound connections from the web host following suspicious WPCafe requests, which may indicate post-exploitation activity
Track plugin version inventory across WordPress estates and flag any installation at or below WPCafe 2.2.32

How to Mitigate CVE-2025-39452

Immediate Actions Required

Update the WPCafe plugin to a version newer than 2.2.32 as soon as the vendor publishes a fix
Audit WordPress user accounts and revoke unnecessary low-privilege accounts that could be abused to reach the vulnerable endpoint
Review web server and WordPress logs for prior exploitation attempts referencing wp-cafe endpoints
Rotate WordPress secrets and database credentials if log analysis indicates wp-config.php was accessed

Patch Information

Consult the Patchstack CVE Analysis for current fixed-version guidance from Arraytics. Patchstack tracks the issue against WPCafe versions through 2.2.32. Apply the vendor patch through the WordPress plugin updater once available.

Workarounds

Deactivate and remove the WPCafe plugin until a patched release is installed
Restrict access to WordPress authentication endpoints with IP allowlisting or multi-factor authentication to limit who can reach the vulnerable handler
Deploy a web application firewall rule that blocks path traversal sequences in parameters destined for wp-cafe AJAX actions
Configure PHP open_basedir to constrain file inclusions to the WordPress installation directory

bash

# Example PHP open_basedir restriction in php.ini
open_basedir = "/var/www/html/:/tmp/"
disable_functions = "exec,passthru,shell_exec,system,proc_open,popen"
allow_url_include = Off
allow_url_fopen = Off
