SQLAdmin: Unvalidated sortBy parameter in `ModelView` bypasses `column_sortable_list`

NVD Description

## Summary `ModelView.sort_query()` uses the attacker-controlled `sortBy` list-view query parameter without checking it against the configured `column_sortable_list` allow-list. The value is resolved with `getattr(model, ...)` and fed into relationship joins and `order_by()`, so a request can sort by **any** column of the model — including ones hidden from `column_list` — and, via a dotted path, by columns of related models. Because row order then reflects the value of an unexposed column, this is an information-exposure **ordering oracle**. ## Root cause `column_sortable_list` is consulted only in the list template to decide which header links to render; the server never enforces it, so removing a column from the UI does not prevent sorting by it. ## Exploitation A single request leaks the relative ordering of an unexposed column; the `asc`↔`desc` reversal confirms rows are ordered by the secret's actual value. Pairing `sortBy` with searchable/filterable columns and pagination can narrow the oracle toward specific values, though value recovery is conditional on having a filterable target column.
