How to fix this CVE

Update the Dør WordPress theme to version 2.4.1 or later to patch the local file inclusion vulnerability that allows attackers to access sensitive files on your server. If you are running PHP with this vulnerable theme, apply the security update immediately and verify the theme version in your WordPress dashboard. This vulnerability has a high severity rating (CVSS 8.1) and affects file handling in the theme's include/require statements.

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

GET|POST request containing parameters like `?file=`, `?include=`, `?path=`, or `?require=` followed by patterns such as `../`, `..\`, `/etc/passwd`, `/proc/`, or `php://`, commonly seen as: `GET /.*\?file=\.\..*` or `GET /.*\?include=.*(/etc/|proc/)`

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 HTTP requests with path traversal sequences (../, ..\ ) in query parameters and POST data. Add rules to deny requests containing file inclusion keywords (file=, include=, require=, path=) combined with system file paths (/etc/passwd, /proc/, /var/). Use a regex pattern like `(?:include|require|file|path)=.*(?:\.\.|/etc/|/proc/|php://)` to catch exploitation attempts.

How to check if you are affected

  1. Step 1: Check your PHP version by running `php -v` on the server or navigating to a phpinfo() page in your WordPress installation
  2. Step 2: In WordPress admin panel, go to Appearance > Themes and verify the Dør theme version is displayed; confirm it is 2.4.1 or higher
  3. Step 3: Search your web server logs (typically /var/log/apache2/access.log or /var/log/nginx/access.log) for suspicious patterns like `/?file=` or `include=` followed by file paths (e.g., `/etc/passwd`, `../`, `../../`)
  4. Step 4: After updating, re-run `php -v` and verify the WordPress theme version again; check that no errors appear in `/var/log/php-fpm/error.log` or similar PHP error logs

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-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.
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-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-2025-47916CVSS 10Invision Community 5.0.0 before 5.0.7 allows remote code execution via crafted template strings to themeeditor.php. The issue lies within the themeeditor controller (file: /applications/core/modules/front/system/themeeditor.php), where a protected method named customCss can be invoked by unauthenticated users. This method passes the value of the content parameter to the Theme::makeProcessFunction() method; hence it is evaluated by the template engine. Accordingly, this can be exploited by unauthenticated attackers to inject and execute arbitrary PHP code by providing crafted template strings.
