What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST|GET /wp-admin/admin-ajax.php?action=.*eventpress.*&file=\.\./|POST|GET requests containing encoded path traversal sequences (%2e%2e%2f or ../) targeting mage-eventpress plugin files

WAF mitigation (if patching is not yet possible)

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

Implement input validation rules to block requests containing path traversal sequences (../, ..\ , %2e%2e%2f, %252e%252e%252f) in parameters passed to eventpress plugin handlers. Block requests to wp-admin/admin-ajax.php with action parameters matching '*eventpress*' that contain file inclusion patterns.

How to check if you are affected

  1. Check installed PHP version: php -v
  2. Verify MagePeople Event Manager plugin version in wp-content/plugins/mage-eventpress/ by examining the plugin header or checking the database option 'mage_eventpress_version'
  3. Search web server logs for suspicious file inclusion patterns: grep -r '\.\./\|\%2e%2e%2f\|file=/.*\.php\|include=/' /var/log/apache2/access.log* /var/log/nginx/access.log*
  4. Confirm patch installation by verifying plugin version matches 4.2.2+ via wp-cli: wp plugin get mage-eventpress --field=version

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.
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-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-2025-46348CVSS 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.
