This is what the WP_Filesystem is for. If you need to write a file,
and you have no direct access, then WP_Filesystem will get credentials
from the user and you can use those to get write access through the

On some setups, with some configurations, yes, it can be a safety
risk. If I'm on the same server as you (shared hosting), then I could,
in theory, overwrite your files in the uploads folder with contents of
my choosing. Depending on the server configuration, of course.
For images, this doesn't matter so much. For CSS or JS files, I can
write code there which will exploit your site when your site includes
it on the page.
