Certain SVG file is not allowed in image only upload directory

[shbchk]

EE 7.2.8

This SVG image can not be uploaded as an image in EE:

I wasn't able to replicate this.

If other SVG files work fine, I suggest that you open this file in code editor and check if it looks like valid XML

[shbchk]

It sure does look like valid XML:

And I just replicated it, using a clean copy of EE 7.2.8.

Here are the steps:

1. Create an upload directory:
   

2. Download this SVG file from Wikipedia: https://upload.wikimedia.org/wikipedia/commons/e/ef/Tribeca_Festival_logo.svg

3. Try to upload it.

PHP Version 7.4.21, btw

Okay, you are right, it's not exactly valid - there is a declaration missing:
<?xml version="1.0" encoding="utf-8"?>

After I added it, EE accepted the file.

I guess, it is the correct behavior. Correct, but do you think it's good? It could be confusing for an editor, to be able to download an image from one website, where it is rendering totally fine, but not to be able to upload it to another.

The file still should be accepted, despite missing <?xml part

There must be something specific in how your server handles MIME types.

Can you do some checks for me?
Try editing system\ee\ExpressionEngine\Library\Mime\MimeType.php file and on line 219 right after $mime = $this->ofFile($path); add this code

dd($mime);

Upload the file and inspect browser console for network requests (because the upload is AJAX).
I'm interested to know what MIME type it returns for you

[shbchk]

I have three EE installs: localhost, Digital Ocean droplet, and a simple virtual hosting for a small website. And everywhere this file wasn't accepted, so this is not because of my setup, I guess :)

With dd($mime); it throws an error in a console.

I made a video!

[intoeetive]

The error is expected in this case; I'd like to see what is returns in Response tab for this request

[shbchk]

Sorry, I'm not a true dev. Yet :)

Here it is:

<pre>string(9) "image/svg"
</pre>

BTW, sometimes, when I click on a file to upload it gets uploaded twice, like in the screenshot below. Not sure though why it is happening and how to replicate it.

[intoeetive]

Interesting. This should just work.

Do you by chance have mimes.php file in system/user/config folder? If yes, what is the contents of it?

Also, you don't have any manipulations (resize / crop) assigned to this upload directory, right?

[shbchk]

No, no mimes.php on both local copies of EE - test install and the dev environment of my website.

I got manipulations on dev environment, but no manipulations on the test installation — it is fresh and clean, just installed for testing purposes.

[intoeetive]

Ok. If you change line 224 (if ($mime == 'image/svg+xml') {) to if (strpos($mime, 'image/svg') === 0) { - does that make things work?

[shbchk]

Yes, now EE is accepting this file!

[intoeetive]

Great! Thanks for helping me debug this

[shbchk]

Always a pleasure, Yuri! Glad to help you and EE :)
