Executive Summary

This vulnerability is a reflected Cross-Site Scripting (XSS) issue found in NocoDB software versions prior to 2026.04.1. It occurs on the Page Leaving Warning page where the query parameters ncRedirectUrl and ncBackUrl are used directly in window.location.href and anchor (&lt;a&gt;) tag bindings without proper validation. This allows an attacker to inject malicious javascript: URIs, potentially executing arbitrary scripts in the context of the user's browser.

Impact Analysis

The reflected XSS vulnerability can allow attackers to execute malicious scripts in the victim's browser. This can lead to theft of sensitive information such as cookies or session tokens, manipulation of web content, or redirection to malicious sites. Since the vulnerability has a CVSS base score of 6.1 with scope changed and impacts on confidentiality and integrity, it poses a moderate security risk.

Mitigation Strategies

To mitigate this vulnerability, update NocoDB to version 2026.04.1 or later, where the reflected XSS issue in the Page Leaving Warning page has been fixed.
