Dragging content to incompatible content pickers bypasses validation and allows saving invalid data

[lrirlu]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

15.1.1

Bug summary

It is possible to drag and drop content from one content picker to another, even if the destination content picker doesn't allow the type of dragged and dropped content.

It is also possible to save and publish in that state.

Specifics

No response

Steps to reproduce

1. Create content types A, B and C
2. Give content type A two content picker properties: One that picks only type B and one that picks only type C
3. Create instances of A, B and C
4. In the instance of A, pick B and C in the content pickers respectively. Save and publish.
5. Now drag the instance of B to the property that picks contents of type C
6. Save and publish

Expected result / actual result

Expected
Client-side: Dragging incompatible content should be blocked with a validation message.
Backend: If validation is bypassed, the backend should reject the request with an appropriate 4xx error.

Actual
Client-side: Dragging is not blocked, and no validation is shown.
Backend: Accepts and processes the invalid data, responding with 200 OK.

Hi there @lrirlu!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂
