Description

Summary A Stored Cross-Site Scripting (XSS) issue previously existed in the Text Widget in Board of Outerbase Studio where unsanitized HTML could be rendered using `dangerouslySetInnerHTML` Steps to Reproduce 1. Create a new dashboard. 2. Add a Text widget. 3. Insert the following payload: ```html ``` Architectural Context Outerbase Cloud and its backend services were discontinued in 2025. The current version of Outerbase Studio operates purely as a client-side application, with dashboard data stored locally in the browser. Impact In the current architecture, the impact is limited to local self-XSS within a user's browser session. The previously described scenarios involving: • authentication token theft • account takeover • database access are no longer applicable since there are no active backend services or authentication tokens. Remediation The unsafe HTML rendering in the Text Widget has been removed in commit https://github.com/outerbase/studio/commit/b06fb85e5967440278d5a815721b360920566ab9 by eliminating the use of dangerouslySetInnerHTML.
