CVE-2025-1661·PHP vulnerability

The HUSKY – Products Filter Professional for WooCommerce plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.3.6.5 via the 'template' parameter of the woof_text_search AJAX action. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

How to fix this CVE

Update the HUSKY – Products Filter Professional for WooCommerce plugin to version 1.3.6.6 or later immediately. This plugin vulnerability allows unauthenticated attackers to include and execute arbitrary PHP files through improper input validation on the 'template' parameter.

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST /wp-admin/admin-ajax.php HTTP/1.1\nContent-Type: application/x-www-form-urlencoded\n.*action=woof_text_search&template=(?:../|..\\|/etc/|c:|\$\{|%252e%252e)

WAF mitigation (if patching is not yet possible)

Add this rule to your WAF to block exploitation attempts while you schedule the patch. 

Block HTTP requests to /wp-admin/admin-ajax.php where the 'action' parameter equals 'woof_text_search' and the 'template' parameter contains path traversal sequences (../, ..\, /etc/, c:, etc.) or begins with non-alphanumeric characters indicating file inclusion attempts.

How to check if you are affected

  1. Step 1: Verify WordPress plugin version: Log into WordPress admin, navigate to Plugins, and check the version of 'HUSKY – Products Filter Professional for WooCommerce' — it should be 1.3.6.6 or later.
  2. Step 2: Check the vulnerable AJAX handler file at wp-content/plugins/woocommerce-products-filter/ext/by_text/index.php for the presence of unsafe file inclusion without proper sanitization of the 'template' parameter.
  3. Step 3: Search web server logs for requests to /wp-admin/admin-ajax.php containing 'action=woof_text_search&template=' followed by file path traversal sequences like '../' or absolute paths.
  4. Step 4: After updating to 1.3.6.6, re-run the vulnerability scan and confirm the plugin version is updated via the WordPress admin dashboard and by checking the plugin's main file header.

CVE-2026-39337CVSS 10ChurchCRM is an open-source church management system. Prior to 7.1.0, critical pre-authentication remote code execution vulnerability in ChurchCRM's setup wizard allows unauthenticated attackers to inject arbitrary PHP code during the initial installation process, leading to complete server compromise.

CVE-2025-62521CVSS 10ChurchCRM is an open-source church management system. Prior to version 5.21.0, a pre-authentication remote code execution vulnerability in ChurchCRM's setup wizard allows unauthenticated attackers to inject arbitrary PHP code during the initial installation process, leading to complete server compromise. The vulnerability exists in `setup/routes/setup.php` where user input from the setup form is directly concatenated into a PHP configuration template without any validation or sanitization. Any parameter in the setup form can be used to inject PHP code that gets written to `Include/Config.php`, which is then executed on every page load. This is more severe than typical authenticated RCE vulnerabilities because it requires no credentials and affects the installation process that administrators must complete. Version 5.21.0 patches the issue.
CVE-2025-46348CVSS 10YesWiki is a wiki system written in PHP. Prior to version 4.5.4, the request to commence a site backup can be performed and downloaded without authentication. The archives are created with a predictable filename, so a malicious user could create and download an archive without being authenticated. This could result in a malicious attacker making numerous requests to create archives and fill up the file system, or by downloading the archive which contains sensitive site information. This issue has been patched in version 4.5.4.
