Can I use Wekan as a CMS?

Here's what it looks like on Trello:

Sometime I could add generating thumbnails of images. It would make loading boards faster.

Embedding YouTube videos was removed from Wekan, because that code had critical security vulnerability https://github.com/wekan/wekan/blob/master/CHANGELOG.md#v385-2020-03-23-wekan-release

I did receive responsible security disclosure in email from security researcher

In that security issue, when some Javascript code was added to card and saved, then after saving and opening card, Javascript could be executed

I have not yet looked is there any safe way to embed YouTube. YouTube has a lot of Javascript.

One possibility would be to download video and upload to Wekan card. But videos are usually very large files, so I think it's not a very good idea.

Another possibility would be to download those videos, and add them to your own webserver as files, and then add links to videos to cards. That would make more sense.

Downloading videos is also a good way to make sure video does not get lost, or some YouTube algorithm does not delete it automatically.

I have all those videos. It is not such a bad idea to have them on my own web server. Anyway, could you make a thumbnail of the video as jpg and then link to youtube?

YouTube has a lot of tracking. For example, I see from adblocker UBlock Origin that some video has 310 trackers, that is amount of blocked tracking urls etc.

Of course you can add links to YouTube. It's just not possible to embed them to card.

For example, with this kind of markdown at card:

- [Nice cat video](https://youtube.com/...)
- [Nice doc vide](https://youtube.com/...)

And video will open in new tab

browser tab

And for those images, you could attach smaller resized images

I mean, don't embed youtube video, but use a simple link to youtube by clicking on an image.

ok

Just a moment I'll try image link

I did not get it working yet

Anyway, text link works

Okay, so when you click on an image nothing would happen. I would have to put a text link, right?

Yes. Wekan and Trello has some features that are at both. Then there are features that only Wekan has (like Swimlanes etc), and some that only Trello has.
