CVE-2026-55650 is a medium-severity cross-site scripting (XSS) vulnerability in @outerbase/studio (npm), affecting versions <= 0.10.2. No fixed version is listed yet.
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 Create a new dashboard. Add a Text widget. Insert the following payload: 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 The previously described scenarios involving: authentication token theft account takeover database access are no longer applicable since there are no active backend services or authentication tokens.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.
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.
CVE-2026-55650 has a CVSS score of 4.4 (Medium). The vector is requires local access, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.
No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

@outerbase/studio (<= 0.10.2)Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.
Kodem's runtime-powered SCA identifies whether CVE-2026-55650 is reachable in your applications. Explore open-source security for your team.

Whether CVE-2026-55650 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns.

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
