Thelia before 3.1.2 and 3.2.x before 3.2.1 contains an unrestricted file upload vulnerability that allows authenticated back-office users to upload PHP files by appending a trailing space to filenames. FileProcessorService validates the raw filename but FileManager::sanitizeFileName() strips the space, storing an executable .php file under public/cache/documents/ for code execution as the web server user.
