In FineCMS through 2017-07-11, application/core/controller/style.php allows remote attackers to write to arbitrary files via the contents and filename parameters in a route=style action. For example, this can be used to overwrite a .php file because the file extension is not checked.
In FineCMS before 2017-07-06, application/lib/ajax/get_image_data.php has SSRF, related to requests for non-image files with a modified HTTP Host header.
