CVE-2026-47378 nocodb CVE debrief

CVE-2026-47378 is a vulnerability in NocoDB, software for building databases as spreadsheets. Prior to version 2026.04.1, public shared-view endpoints exposed values from columns that the view owner had hidden. This occurred 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. The vulnerability is fixed in version 2026.04.1. Users should update to the latest version to prevent potential exposure of sensitive data.

Who should care

Users of NocoDB, especially those who use public shared-view endpoints, should be aware of this vulnerability. If you are using a version prior to 2026.04.1, you should update immediately to prevent potential exposure of sensitive data. Additionally, administrators and security teams responsible for NocoDB instances should prioritize updating to the latest version.

Technical summary

The vulnerability in NocoDB arises from the public shared-view endpoints' exposure of hidden column values. This occurs through three main paths: 1) The groupBy function returns raw values for any column specified in the request, 2) Filter and sort arrays can operate on hidden columns, allowing for boolean-blind extraction, and 3) The related-data list accepts arbitrary link-column IDs from other tables within the same base. These issues were addressed and fixed in version 2026.04.1 of NocoDB. The vulnerability has a CVSS score of 6.9 and is classified as MEDIUM severity.

Defensive priority

Defenders should prioritize updating NocoDB to version 2026.04.1 or later. In the meantime, restrict access to public shared-view endpoints and closely monitor for any suspicious activity.

Recommended defensive actions

  • Update NocoDB to version 2026.04.1 or later.

  • Closely monitor for any suspicious activity related to shared-view endpoints.
  • Review and adjust permissions for view owners to ensure proper data access controls.
  • Consider implementing additional security measures, such as data encryption and access logging.
