How to fix this CVE

Update FreeScout to version 1.8.212 or later to address a customer visibility enforcement flaw in the merge operation. This vulnerability allows users with partial visibility restrictions to potentially access customer records they should not be able to view during customer merging operations. Ensure your PHP environment runs the latest patched version of FreeScout and test the customer merge functionality after deployment.

How to check if you are affected

  1. Check FreeScout version: Visit the admin panel or run `grep 'VERSION' /path/to/freescout/config/app.php` to confirm the installed version
  2. Verify limit_user_customer_visibility setting: Query the FreeScout database with `SELECT * FROM settings WHERE name LIKE '%limit_user_customer%'` to confirm the setting exists
  3. Review customer merge logs: Check `/path/to/freescout/storage/logs/` for any merge operations involving multiple customers and cross-reference with user permission logs
  4. Confirm patch application: After updating to 1.8.212+, verify the fix by checking the commit hash in `.git/refs/heads/master` or reviewing the changelog in `/path/to/freescout/CHANGELOG.md`

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-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.
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.
