Official description

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, 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. 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. This vulnerability is fixed in 2026.05.1.
