CVE-2026-27636
February 25, 2026
FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.206, FreeScout's file upload restriction list in "app/Misc/Helper.php" does not include ".htaccess" or ".user.ini" files. On Apache servers with "AllowOverride All" (a common configuration), an authenticated user can upload a ".htaccess" file to redefine how files are processed, enabling Remote Code Execution. This vulnerability can be exploited on its own or in combination with CVE-2026-27637. Version 1.8.206 fixes both vulnerabilities.
