Hi Team,

We recently ran security scan on our web application which using "https://kendo.cdn.telerik.com/2020.2.513" Version.

and we encountered one scenario where Cross Site script executed even though we implemented encode and decode.

Scenari: User opens editor -> Clicks Insert Link Option.

We filled URL, Text inputs and for Tooltip fields we input Cross Site Script i.e (">">">"><script>alert(document.cookie);</script>)

and we clicked INSERT.

Basically the Tooltip field will break the anchor tag title parameter and script will execute.

Though we have implemented HTML encode and Decode we still experiencing this alert popup with cookie data while encode and Save and also Decode and Show.

OR
Please let us know.

How to restrict user to input only Alphanumeric Values into the fields "Text", and "ToolTip" when user clicks "Insert Link" option on Kendo tool Editor (CK Editor).

Hi,

Bullets are not removed when content is deleted.

1. Create text editor on a div
2. Input some text
3. Make it bold and underline
4. Make it bulleted
5. Add few more bullets
6. Select all bullets
7. Press backspace

Observe that two bullet points remain

Hi,

We are facing an issue as follows.

1. We type some ordered or unordered list and we move cursor one left or right.

2. We do select all and backspace to delete entire list.

Issue: First index or bullet never gets deleted does not matter how many times backspace is clicked. On inspecting dom we can see list structure is retained and does not get deleted.

Please find attached video.

Thanks

Bug report

Then you open the color/background color tools in an Inline Editor, closing the tools by clicking randomly on the page doesn't close the Editor popup.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/VMVasaJO/5
2. Open the color or the background color tool
3. Click outside of the popups or the Editor
4. You can compare the behaviour with other tools that have a popup, e.g. the formatting tool

Current behavior

The inline Editor remains open when closing the color/background tool popups

Expected behavior

The inline Editor should close when the popups and the Editor lose focus

Environment

• Kendo UI version: 2024.4.1112
• Browser: [all]

I can use the Print-Dialog (Print-Icon in the Editor)  only once.

If I try to use it again nothing happens. If I do a page reload everything works fine for one time again.

When trying to navigate the toolbar of the editor with a keyboard, the focus is stuck/not working for color pickers.

When using Tab(or RightArrow) from the left the focus is stuck on the first colorpicker.

When using Shift+Tab(or LeftArrow) from the right the focus is stuck on the last tool before the colorpicker.

See DOJO: https://dojo.telerik.com/aKOKOwiP

Bug report

If you toggle the formatting marks in an Inline Editor, the marks are toggled for every Editor on the page. Additionally, if the content is scrollable, the marks remain stationary when you scroll through the content.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/@martin.tabakov@progress.com/AFiTuKif/2
2. Open the top inline Editor
3. Toggle the formatting marks
4. Scroll the Top Inline Editor

Current behavior

The formatting marks are toggled for each Editor on the page, and the arrow formatting mark remains stationary if you scroll through the content.

Expected/desired behavior

The formatting marks should be toggled for the target Editor only, and the formatting mark shouldn't scroll.

Hello,

I have an issue when I use the drag and drop of a picture in the kendo Editor inline.

Let me explain it :

1) Go to : https://runner.telerik.io/fullscreen/uWosAbib (It's the standard example on your site) on chrome 123

2) Select the last editor "Rich UI Widgets for..."

3) Take a file of a picture on your computer and drop it on the first editor "Comprehensive HTML5/..."

Two things :

* The file open on a new tab browser instead of to be added to the html of the first editor

* There is a message in the debug tools (The stack trace is added in the Attach Files)

Uncaught TypeError: Cannot read properties of null (reading 'nodeType')
    at init.index (kendo.all.js:135127:1)

Another element, if you don't select and just drag and drop it's work.

Thank you for your awesome framework and good luck with the correction !

Bug report

When setting a special font of a given paragraph in the Editor component, if the "x" of the Font dropdown is pressed it will reset the font of this text to the default one. If we then want to change the format of a given paragraph(make it bold for example), we select the paragraph and click on the "Bold" button. The text which is being bolded is the one which font was previously reset, not the selected text which we expect to become bold.

Reproduction of the problem

1. Open this Dojo and select a random text in the Editor
2. Change the font of the selected text by choosing one from the "Fonts" dropdown
3. After changing the font keep the text selection and click on the "x" in the "Fonts" dropdown. The font of the selected paragraph will be reset to the default one.
4. Select a random text chunk in the Editor and click on the "Bold" button.
5. See that the bolded text is not the one we expect to be, but the text which font we've reset.

The reported behavior is applicable to all styles - bold, italic, underline, text alignment, ul, ol.

Current behavior

When changing the style of a given selected text, after there was a font reset in the Editor, the new formatting we set is being applied on the text which font was reset, not on the selected one.

Expected/desired behavior

No matter the operations performed in the Editor when formatting a selected text, the format changes should be applied to the selected text only.

Bug report

Using Edge/Chrome, upon pasting underline text in the Kendo UI Editor, the content is rendered underline, but the UI doesn't highlight the button. In turn, if the user toggles the underline style for parts of the text, it doesn't work. At this point, the button is now highlighted for the part, but switching back to no underline style doesn't have any effect regarding the rendering. Removing the style for the whole line does work as expected.

Reproduction of the problem

1. Open Editor demo and enter some text, containing an underline.

2. Copy the entered text and reload page
3. Paste content at the start of the document. The text is not recognized as underline text

4. Select part of the text and toggle underline. Part of the text is recognized as underlined text now.

Expected/desired behavior

The underlined text decoration should be recognized by the UI and display.

Additional Notes

As a comparison, here is the content after paste:

Edge/Chrome

<p><span style="text-decoration-line:underline;">some text with underline</span></p>

FireFox - which is working

<p><span style="text-decoration:underline;">some text with underline</span></p>

6. This is very inconvenient.

Bug report

The ColorPickers in the Editor allow the user to change the text color or the background color of a selection in the component. When the Editor is working in Inline mode, if you select a text and manually enter a value in the HEX input of a ColorPicker, the pre-selected text is no longer selected. No text is colored inside the Editor.

Reproduction of the problem

1. Open this Dojo and run it
2. Select a text in the inline Editor
3. Open one of the ColorPickers and enter a value in the HEX input
4. Apply the HEX value

Current behavior

The ColorPicker closes. The selected text in the Editor before opening the ColorPicker is no longer selected. No text in the Editor is in the color entered in the HEX editor.

Expected/desired behavior

Clicking on the Apply button of the ColorPicker, after a HEX value is entered, should close the ColorPicker and color the pre-selected text. This correct behavior can be observed in the second Editor in the linked above Dojo example.
