## 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 <img src=x onerror="alert('XSS Executed\nToken: ' + localStorage.getItem('ob-token'))"> ``` ### 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 The previously described scenarios involving: - authentication token theft - account takeover - database access are no longer applicable since there are no active backend services or authentication tokens.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.

AI coding agents often install or upgrade packages automatically in npm. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
