CVE-2024-26152

Estado: AnalizadaMedia (6.1)—

### 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. ![Create a project](https://github.com/HumanSignal/label-studio/assets/3943358/9b1536ad-feac-4238-a1bd-ca9b1b798673)

2.
