A cross-site scripting (XSS) vulnerability has been identified in Argilla versions through 2.8.0. The issue arises in the annotation feature, specifically within the Sandbox.vue component. The vulnerability allows for remote exploitation by manipulating the template argument of custom field settings. When the template is rendered into an iframe without a sandbox attribute, any embedded scripts execute with the same-origin policy, gaining full access to the application DOM, the user's session, and localStorage. This vulnerability was reported to the Argilla project, but no response has been received yet.
