Unauthenticated open redirect via protocol-relative hash path
Published Jun 23, 2026 · Updated Jun 23, 2026
Open redirect in NocoDB before 2026.04.1 allows remote attackers to send visitors to an attacker-controlled site via a crafted link. The client-side hashRedirect plugin passes a hash-derived path to window.location.replace() after a single-slash prefix check that also accepts protocol-relative URLs. No authentication is required, but a victim must open the link; the redirect can place the victim on a phishing page without altering the NocoDB instance.
