How to Fix CVE-2026-46547

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: Latest secure release 
npm install nocodb@Latest secure release
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-2026-46547, 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 the patched release), 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. 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 A reflected XSS vulnerability exists in the Page Leaving Warning page. The `ncRedirectUrl` and `ncBackUrl` query parameters are used in `window.location.href` and `<a>` tag bindings without validation, allowing `javascript:` URI injection. ### Details `PageLeavingWarning.vue` reads `ncRedirectUrl` and `ncBackUrl` directly from the route query without validation. When `isSameOriginUrl()` returns `false` (as it does for `javascript:` URIs), the raw URL is assigned to `window.location.href`, executing arbitrary JavaScript. The redirect URL is also bound directly to an `<a>` tag's `href` attribute. ### Impact An attacker can execute arbitrary JavaScript in the context of the NocoDB application by sending a crafted link to a victim. No authentication is required. ### Credit This issue was reported by [@naoyashiga](https://github.com/naoyashiga).
