Description

Summary

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.

Details

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. All three handlers now also fetch the shared view's column entries and reject the request unless the matching entry has show=true. The four public relation routes covered by the fix are:

GET /api/v2/public/shared-view/:uuid/rows/:rowId/mm/:columnId (many-to-many)
GET /api/v2/public/shared-view/:uuid/rows/:rowId/hm/:columnId (has-many)
GET /api/v2/public/shared-view/:uuid/rows/:rowId/{ln,om}/:columnId (links / one-to-many — both share the many-to-many handler)
GET /api/v2/public/shared-view/:uuid/nested/:columnId (form/gallery picker)

Impact

Anyone holding a share UUID could enumerate the full set of linked records for any hidden LTAR column on the view's table by calling the relation endpoint directly, even when the same column was correctly omitted from the public /rows response.
