Summary An authenticated user with column-create permission can inject SQL into the bulk groupBy endpoint by setting a column's title to a SQL fragment. Details The bulk groupBy path in "group-by.ts" builds three database-specific "knex.raw()" aggregations that interpolate the request's "column_name" directly into the SQL string. Column lookup in "data-table.service.ts" matches on both the sanitized "column_name" field and the free-text "title", so a title containing a SQL fragment bypasses the public endpoint's existing column allowlist and reaches the query builder unescaped. Impact SQL injection against the connected database with read access to any expression an attacker can place in a column title. Exploitation requires an authenticated session with permission to create or rename columns. Credit This issue was reported by "@geo-chen" (https://github.com/geo-chen).
