Summary
A reflected XSS vulnerability exists in the Page Leaving Warning page. The ncRedirectUrl and ncBackUrl query parameters are used in window.location.href and <a> tag bindings without validation, allowing javascript: URI injection.
Details
PageLeavingWarning.vue reads ncRedirectUrl and ncBackUrl directly from the route query without validation. When isSameOriginUrl() returns false (as it does for javascript: URIs), the raw URL is assigned to window.location.href, executing arbitrary JavaScript. The redirect URL is also bound directly to an <a> tag's href attribute.
Impact
An attacker can execute arbitrary JavaScript in the context of the NocoDB application by sending a crafted link to a victim. No authentication is required.
