How to Fix CVE-2026-28359

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: 0.301.3 
npm install nocodb@0.301.3
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-2026-28359, 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 0.301.3), 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 user with Editor role can inject arbitrary HTML into Rich Text cells by bypassing the TipTap editor and sending raw HTML via the API. ### Details The TipTap editor sanitizes HTML client-side, but the backend stores raw HTML without server-side sanitization. The stored content is rendered via `v-html` in `TextArea.vue` through `NcMarkdownParser.parse()` which performs no sanitization. ### Impact Stored XSS — malicious scripts execute for any user viewing the cell. ### Credit This issue was reported by [@Akokonunes](https://github.com/Akokonunes).
