Stored Cross-Site Scripting (XSS) in Sisense BloX widgets, in all versions, both on Sisense Cloud and in self-hosted deployments, allows an authenticated user with the Designer or Administrator role to execute JavaScript code in the browser of another user who opens the dashboard, via HTML or JavaScript code inserted into BloX widget fields, such as ‘desc’ and ‘text’.

Stored cross-site scripting (XSS) in BloX widgets. The /api/dashboards/<id>/widgets/<id> API accepts HTML and JavaScript content in the ‘desc’ and ‘text’ parameters. The code entered is executed in the browser when the widget is rendered, which could compromise the confidentiality of the information accessible in that context.
