Please note that the Attributes Plugin has unsanitized fields leading to possible XSS exploits, as you can see in the attached screenshot.

Also, there's the following notice:
PHP Notice:  Undefined index: values in \oc-content\plugins\attributes\functions.php on line 807
Plugin version: 2.4.0
PHP Version: 7.2.34

Hoping for a quick fix.
Thanks!

Thank you, will be fixed in next update.

@Frosticek
Any news on this?

Security issues (big or small) should have top priority, as they can be exploited with devastating consequences...

Also, the first rule of secure programming is:
Never Trust User Input


Thanks!

It was fixed some time ago, just was not re-uploaded.
You can find fixes now.
