nocodbnpmDescription
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nocodb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of nocodb has shipped for CVE-2026-46547 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
