CVE-2025-67886
Bitrix24 through 25.100.300 allows Remote Code Execution because an actor with SOURCE/WRITE permissions for the Translate Module can upload and execute code by sending a PHP file and a .htaccess file.
Does this matter?
Lower severity and a low EPSS score (1.03%). Track it; it rarely justifies an emergency change on its own.
Description
Bitrix24 through 25.100.300 allows Remote Code Execution because an actor with SOURCE/WRITE permissions for the Translate Module can upload and execute code by sending a PHP file and a .htaccess file. NOTE: this is disputed by the Supplier because this is intended behavior for the high-privileged users who can upload new translated pages to the website.
