CVE-2024-5147·PHP vulnerability

The WPZOOM Addons for Elementor (Templates, Widgets) plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.1.37 via the 'grid_style' parameter. 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 WPZOOM Addons for Elementor plugin to version 1.1.38 or later to patch the local file inclusion vulnerability in the grid_style parameter. If you are running PHP with this plugin installed, apply the update immediately as this flaw allows unauthenticated attackers to include and execute arbitrary PHP files on your server. After updating, verify the plugin version and test your site to ensure functionality is preserved.

sudo dnf update php php-common php-cli

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST /wp-admin/admin-ajax.php?action=wpzoom_elementor_ajax_posts_grid - Request body containing 'grid_style' parameter with path traversal sequences (e.g., '../', '..\', '%2e%2e', or absolute file paths like '/etc/passwd' or 'php://filter/convert.base64-encode/resource=...'); Successful exploitation results in HTTP 200 with PHP execution output or file contents in response

WAF mitigation (if patching is not yet possible)

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

Block requests to /wp-admin/admin-ajax.php with action=wpzoom_elementor_ajax_posts_grid that contain grid_style parameters with special characters, path traversal patterns (../, ..\ ), or PHP wrappers (php://, data://, file://). Implement strict input validation requiring grid_style to match whitelisted CSS class names only.

How to check if you are affected

  1. Check installed WPZOOM plugin version: grep -r 'Version:' /path/to/wordpress/wp-content/plugins/wpzoom-elementor-addons/wpzoom-elementor-addons.php | head -1
  2. Verify if the vulnerable grid_style AJAX endpoint is accessible: curl -s http://your-site/wp-admin/admin-ajax.php?action=wpzoom_elementor_ajax_posts_grid | grep -i grid_style
  3. Search WordPress debug logs for suspicious grid_style parameter usage: grep -i 'grid_style' /path/to/wordpress/wp-content/debug.log
  4. Confirm the patch by checking if plugin version is 1.1.38 or higher and test the AJAX grid functionality without errors

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.
