Description

NocoDB: Hidden Column Exposure in Public Shared View Endpoints

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.
