How to Fix CVE-2026-47376

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-2026-47376, 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-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 The password-reset page rendered the URL token directly into a JavaScript string literal in a server-rendered EJS template. EJS `<%= %>` HTML-entity-encodes a fixed set of characters but does not escape single quotes or backslashes, so a crafted token could break out of the JS string context and execute attacker-controlled script in the NocoDB origin. Triggering required only that a victim follow a malicious password-reset link. ### Details The vulnerable template embedded the token as: ```ejs token: '<%= token %>', ``` A token containing `';alert(document.cookie);//` closes the single-quoted string and runs arbitrary JavaScript. The fix moves the token into an HTML attribute (`data-token="…"`) and reads it from `dataset.token` at runtime, so EJS's HTML-entity escaping is sufficient. ### Impact - Reflected XSS in the NocoDB origin via a phished password-reset URL. - No authentication required to trigger; affects any user who clicks the crafted link. - Same-origin script can read auth state and act on the victim's behalf. ### Credit This issue was reported by [@fg0x0](https://github.com/fg0x0).
