Budibase before 3.41.3 Authorization Bypass via datasources/query
Description

Budibase before 3.41.3 fails to enforce per-table role restrictions on the POST /api/datasources/query endpoint, allowing low-privilege BASIC users to read, create, update, or delete rows in any table regardless of configured permissions. Attackers with BASIC role can submit crafted query requests with target table identifiers to bypass table-level access controls and manipulate restricted data.
