How to Fix CVE-2026-47377

To remediate this vulnerability, upgrade all affected NocoDB dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

nocodb fixed: 2026.04.1 
npm install nocodb@2026.04.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls nocodb

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-47377, inspect your project dependencies using npm:

npm ls nocodb

Analyze the terminal output to locate any version of NocoDB in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.04.1), your application is affected.

Note: The npm ls nocodb command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In NocoDB, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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`: ```ts 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. ### Credit This issue was reported by [@fg0x0](https://github.com/fg0x0).
