What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST|GET /wp-admin/admin-ajax.php.*component=.*(\.\./|%2e%2e|php:|file:|phar:)

WAF mitigation (if patching is not yet possible)

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

Implement WAF rules to block requests containing the 'component' parameter with path traversal sequences (../, %2e%2e, encoded dots) or protocol handlers (file:, php:, phar:). Example: Block requests matching pattern: /wp-admin/admin-ajax.php.*component.*[./]{2,}|component.*(file:|php:|phar:)

How to check if you are affected

  1. Check installed WordPress plugin version: grep 'Version:' /var/www/html/wp-content/plugins/grow-by-tradedoubler/grow-by-tradedoubler.php
  2. Verify the plugin's main file exists and examine it for vulnerable component parameter handling: find /var/www/html/wp-content/plugins/grow-by-tradedoubler -name '*.php' | head -1
  3. Search web server logs for exploitation attempts using the component parameter: grep -i 'component=' /var/log/apache2/access.log | grep -E '(\.\./|%2e%2e|php:|file:)'
  4. Confirm the plugin has been updated to 2.0.22 or later: curl -s https://api.wordpress.org/plugins/info/1.0/grow-by-tradedoubler.json | grep version

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.

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. The "$dbPassword" variable is not sanitized. This vulnerability exists due to an incomplete fix for CVE-2025-62521. This vulnerability is fixed in 7.1.0.
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-2024-5932CVSS 10The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.14.1 via deserialization of untrusted input from the 'give_title' parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to execute code remotely, and to delete arbitrary files.
