NocoDB: Open Redirect via Hash Fragment in hashRedirect Plugin
Summary
The client-side hashRedirect plugin called window.location.replace() on a path extracted from the URL hash fragment after only checking hashPath.startsWith('/'). Protocol-relative URLs (//attacker.com/…) also satisfy that check, so a crafted link such as https://nocodb.example/#//attacker.com/phishing silently redirected visitors to an attacker-controlled origin.
Details
In packages/nc-gui/plugins/hashRedirect.client.ts, the plugin extracted the hash content and normalised it into cleanUrl:
let cleanUrl = hashPath.startsWith('/') ? hashPath : `/${hashPath}`
if (hashQuery) cleanUrl += `?${hashQuery}`
window.location.replace(cleanUrl)startsWith('/') returns true for //attacker.com/..., which browsers interpret as a protocol-relative absolute URL. No hostname check was performed before the redirect. The fix adds an early if (/^\/[/\\]/.test(hashPath)) return to reject protocol-relative paths.
Impact
- Open redirect from any NocoDB origin to an attacker-controlled domain.
- No authentication required; the attack lands the victim on an attacker-controlled page that may impersonate a NocoDB login.
