CVE-2026-47377
Received Received - Intake
Stored XSS via Malicious URL Redirect in NocoDB

Publication date: 2026-06-23

Last updated on: 2026-06-23

Assigner: GitHub, Inc.

Description
NocoDB is software for building databases as spreadsheets. Prior to 2026.04.1, 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 silently redirected visitors to an attacker-controlled origin. This vulnerability is fixed in 2026.04.1.

Executive Summary

This vulnerability exists in NocoDB versions prior to 2026.04.1 in the client-side hashRedirect plugin. The plugin uses window.location.replace() to redirect users based on a path extracted from the URL hash fragment, but it only checks if the path starts with a '/'.

Because protocol-relative URLs (which start with //) also satisfy this check, an attacker can craft a link that causes the plugin to silently redirect visitors to an attacker-controlled website without their knowledge.

This issue is fixed in version 2026.04.1.

Impact Analysis

This vulnerability can lead to users being silently redirected to malicious websites controlled by attackers.

Such redirections can be used for phishing attacks, stealing user credentials, delivering malware, or other malicious activities that compromise user security and trust.

Mitigation Strategies

To mitigate this vulnerability, upgrade NocoDB to version 2026.04.1 or later, where the issue with the hashRedirect plugin has been fixed.
