## Description

Teable before 2026-06-15T04-43-24Z.1912 contains an improper access control vulnerability that allows anonymous attackers to access hidden field data by supplying arbitrary field IDs in the projection parameter of the share view records endpoint. Attackers can enumerate hidden field IDs from share metadata and specify them in projection parameters to read field values that are intended to be restricted from public view.
