How to fix this CVE

Update the GEO my WP WordPress plugin to version 4.5.0.2 or later immediately to patch the arbitrary file inclusion vulnerability that allows unauthenticated remote code execution. If you cannot update the plugin immediately, disable or remove it from your WordPress installation until the patch can be applied. Verify that PHP itself is running the latest security-patched version available for your distribution.

sudo dnf update php

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

GET|POST requests containing file inclusion payloads targeting plugin directory with parameters such as (?:file|include|path)=(?:\.\.\/|\.\.\\|%2e%2e%2f) or paths attempting to access /etc/passwd, wp-config.php, or other sensitive files; also look for POST requests with multipart form data attempting to upload executable files to plugin directories

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 file traversal sequences (../, ..\, %2e%2e%2f, %252e) in query parameters and POST bodies targeting /wp-content/plugins/geo-my-wp/. Additionally, restrict execution permissions on plugin directories and disable dynamic PHP execution in upload directories.

How to check if you are affected

  1. Run `php -v` to check the installed PHP version and ensure it is the latest patched release for your distribution.
  2. Check the GEO my WP plugin version by navigating to WordPress Admin > Plugins and locating 'GEO my WP'; verify the version is at least 4.5.0.2.
  3. Review web server access logs for suspicious file inclusion attempts targeting PHP scripts, looking for patterns like `?file=` or `?include=` parameters with paths outside the plugin directory (e.g., `GET /wp-content/plugins/geo-my-wp/ HTTP/1.1` followed by unusual parameter values).
  4. Confirm the fix by re-running `php -v` and re-checking the GEO my WP plugin version in WordPress to ensure it displays 4.5.0.2 or higher.

How do I check if my server is vulnerable to CVE-2024-6330?

In WordPress Admin, go to Plugins and check the GEO my WP version; if it shows any version below 4.5.0.2, your site is vulnerable. You can also inspect the plugin's readme.txt file in `/wp-content/plugins/geo-my-wp/` for the version number.

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.
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.
