How to Fix CVE-2026-47378

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-2026-47378, 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-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. 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 Public shared-view endpoints exposed values from columns that the view owner had hidden, via three independent paths: groupBy returned raw values for any column named in the request, filter and sort arrays operated on hidden columns enabling boolean-blind extraction, and the related-data list accepted arbitrary link-column IDs from other tables in the same base. ### Details A new `sanitizeListArgsForPublicView` helper now strips request keys that should never be caller-controlled (e.g. `getHiddenColumn`, `nested`), parses `where` clauses against a restricted alias map that only contains visible columns, and recursively removes filter/sort entries whose `fk_column_id` is not in the visible set. `validateGroupByColumnNames` and `validateGroupColumnId` reject groupBy requests whose `column_name` (CSV-style) or `groupColumnId` is not in the visible or group-by column set. `relDataList` now checks `column.fk_model_id === currentModel.id` before resolving the linked table, matching the pre-existing check on `publicMmList` and `publicHmList`. ### Impact Anyone with a shared-view UUID could enumerate hidden-column values directly (via groupBy), confirm hidden-column values by observing row counts (via filter), or read records from unrelated tables in the same base (via the related-data list). No authentication was required. ### Credit This issue was reported by [@0xBassia](https://github.com/0xBassia). It was independently reported by [@b-hermes](https://github.com/b-hermes).
