How to Fix CVE-2026-47279

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-2026-47279, 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-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. 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 public shared-view relation endpoints accepted a caller-supplied column ID without verifying that the column was visible in the shared view, so anyone holding a share UUID could read links from any LTAR column on the view's table — including columns the view owner had hidden. ### Details `publicMmList`, `publicHmList`, and `relDataList` already ensured that the requested column belonged to the view's model, but did not check the view-column entry's `show` flag. All three handlers now also fetch the shared view's column entries and reject the request unless the matching entry has `show=true`. The four public relation routes covered by the fix are: - `GET /api/v2/public/shared-view/:uuid/rows/:rowId/mm/:columnId` (many-to-many) - `GET /api/v2/public/shared-view/:uuid/rows/:rowId/hm/:columnId` (has-many) - `GET /api/v2/public/shared-view/:uuid/rows/:rowId/{ln,om}/:columnId` (links / one-to-many — both share the many-to-many handler) - `GET /api/v2/public/shared-view/:uuid/nested/:columnId` (form/gallery picker) ### Impact Anyone holding a share UUID could enumerate the full set of linked records for any hidden LTAR column on the view's table by calling the relation endpoint directly, even when the same column was correctly omitted from the public `/rows` response. ### Credit This issue was reported by [@leduckhuong](https://github.com/leduckhuong).
