GHSA-4W6R-5C2J-QF5F
Vulnerability from github – Published: 2026-06-05 16:03 – Updated: 2026-07-20 21:19Summary
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.
