Descripción
*** Pendiente de traducción *** Incorrect Authorization vulnerability in ash-project ash_postgres allows a user to read another tenant&#39;s record through a skipped upsert.<br />
<br />
When Ash.bulk_create/4 or a single create runs as an upsert with return_skipped_upsert?: true and the upsert is skipped (for example because its upsert_condition does not hold), AshPostgres.DataLayer reads the existing row back by the upsert identity in do_bulk_create/3 and upsert/4. That lookup did not apply the resource&#39;s attribute multitenancy, so on a resource using strategy :attribute it could match and return the row of another tenant with the same identity values, exposing its fields to the caller.<br />
<br />
This issue affects ash_postgres: from 2.6.22 before 2.15.2.
