Published

Twenty is an open-source CRM (customer relationship management) platform. Prior to 2.22.0, field-level read permission is enforced on selected output fields but not on GraphQL or REST filter predicates. A workspace member or API key with permission to read an object but not a particular field can reference that denied field in direct filters, relation filters, or persisted view filters. The resulting totalCount and row presence reveal whether guesses match the real column, forming a boolean/count oracle that can reconstruct denied field values for records exposed by the principal's row-level policy. This issue is fixed in version 2.22.0.
