Description
Outerbase Studio is a lightweight browser-based database GUI supporting PostgreSQL, MySQL, and SQLite. In version 0.10.2 and earlier, TextComponent in src/components/chart/index.tsx renders unsanitized Text Widget content through dangerouslySetInnerHTML, allowing injected markup with script-capable event handlers to execute when the widget is displayed. Outerbase Cloud and its backend services were discontinued in 2025, and the current architecture uses local browser dashboard storage, so the impact is limited to local self-XSS. Authentication token theft, account takeover, and backend database access are not applicable to the current architecture. No fixed release is available as of this review.
