  "details": "## Summary\n\nA 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`\n\n### Steps to Reproduce\n\n1. Create a new dashboard.\n2. Add a **Text widget**.\n3. Insert the following payload:\n\n```html\n\u003cimg src=x onerror=\"alert(\u0027XSS Executed\\nToken: \u0027 + localStorage.getItem(\u0027ob-token\u0027))\"\u003e\n```\n\n### Architectural Context\n\nOuterbase Cloud and its backend services were discontinued in 2025.\n\nThe current version of Outerbase Studio operates purely as a client-side application, with dashboard data stored locally in the browser.\n\n### Impact\n\nIn the current architecture, the impact is limited to local self-XSS within a user\u0027s browser session.\nThe previously described scenarios involving:\n\n- authentication token theft\n- account takeover\n- database access\n\nare no longer applicable since there are no active backend services or authentication tokens.\n\n### Remediation\n\nThe unsafe HTML rendering in the Text Widget has been removed in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.",
