Hello, I'm not sure where is the problem - do you have a problem with base64image plugin?

[SuperPat45]

base64image is not the problem,
It is ckeditor who is unable to paste an image content in a clipboard without the uploadimage plugin.
We can insert only an image file copied in the clipboard

Ok. I managed to reproduce this issue also in Chrome using CDEditor CDN on MacOS: press CTRL+CMD+SHIFT+3 which will store print screen in clipboard and then try to paste into editor -nothing will happen (to compare try the same e.g. in File Upload demo - but note it's config doesn't insert image in base64 format). Could you tell why you don't use uploadimage plugin?

[SuperPat45]

I currently don't use uploadimage because I need image inserted as base64 in the HTML. This is why I use the base64image plugin.

@SuperPat45 since for image handling you are using base64image plugin isn't it the issue with the plugin itself that it can't correctly handle images in such case.

The base64image plugin is the 3rd-party plugin so the issue should be reported to plugin authors directly (see https://ckeditor.com/cke4/addon/base64image).

It would be better if I didn't have to use any image plugins to paste image content of file.
It worked fine in ckeditor 4.13 but only on firefox.

Ok, I see the main point of this issue is that it worked fine without any additional plugins on Firefox with CKEditor 4 4.13.0 and stopped working in 4.13.1. Tested and confirmed that on Windows 7 with Firefox 72.

It doesn't work in Chrome like that (both in 4.13.0 and 4.13.1) so Firefox is probably the only supported browser which can handle this situation natively.

I suppose, we could treat it as a regression in Firefox then. And our suspect would be #3639.
