How to Fix CVE-2026-47383

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: 2026.05.1 
npm install nocodb@2026.05.1
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-2026-47383, 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 2026.05.1), 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 An authenticated commenter could store HTML in row comments that executed as script when other users hovered over the comment in the expanded form view. ### Details The comment write paths persisted the raw comment body with no server-side sanitisation; the expanded-form sidebar then rendered the stored body and fed its `data-tooltip` attribute to Tippy with `allowHTML: true`. Even when the editor stripped script tags at write time, attribute-level payloads re-entered the DOM as live HTML on hover. ### Impact Stored Cross-Site Scripting against any user who views the affected row. Script runs in the NocoDB origin with the victim's session and can read the auth JWT from `localStorage`. Authentication and comment permission are required. ### Credit This issue was reported by [@DavidCarliez](https://github.com/DavidCarliez). It was independently reported by [@Mouhebbenelwafi](https://github.com/Mouhebbenelwafi).
