How to fix this CVE

Update the Cryptocurrency Widgets For Elementor plugin to version 1.6.5 or later, which resolves a local file inclusion vulnerability that could allow attackers to read sensitive files from your server. If you are running PHP directly without the plugin, ensure your PHP installation is up-to-date and review any custom include/require statements in your code to prevent similar issues.

sudo dnf update php

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

GET request patterns containing multiple ../ sequences or paths attempting to access /etc/passwd, /etc/shadow, or similar system files in query parameters (e.g., `?file=../../../../etc/passwd` or variations thereof)

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 path traversal sequences (../ or ..\) in query parameters and POST data; additionally, restrict access to sensitive files by denying requests that attempt to include system configuration paths like /etc/*, /proc/*, or /sys/* through the web application.

How to check if you are affected

  1. Step 1: Check installed PHP version with `php -v` to confirm your current installation level.
  2. Step 2: If using the Cryptocurrency Widgets For Elementor plugin, verify the version by checking wp-content/plugins/cryptocurrency-widgets-for-elementor/readme.txt or the plugin details in wp-admin/plugins.php.
  3. Step 3: Search web server logs (Apache: /var/log/apache2/access.log, Nginx: /var/log/nginx/access.log) for suspicious file paths in query strings containing ../ or /etc/ patterns.
  4. Step 4: After updating, confirm the fix by re-running `php -v` or plugin version check to verify the new version is active; restart PHP-FPM or your web server to ensure changes take effect.

CVE-2026-28289CVSS 10FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. A patch bypass vulnerability for CVE-2026-27636 in FreeScout 1.8.206 and earlier allows any authenticated user with file upload permissions to achieve Remote Code Execution (RCE) on the server by uploading a malicious .htaccess file using a zero-width space character prefix to bypass the security check. The vulnerability exists in the sanitizeUploadedFileName() function in app/Http/Helper.php. The function contains a Time-of-Check to Time-of-Use (TOCTOU) flaw where the dot-prefix check occurs before sanitization removes invisible characters. This vulnerability is fixed in 1.8.207.
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.
