CVE-2026-115635
>_ Opis
Tłumaczenie automatyczne – może zawierać nieścisłości.
Luka w zabezpieczeniach nieprawidłowej autoryzacji w projekcie ash ash_postgres umożliwia użytkownikowi odczytanie rekordu innego dzierżawcy poprzez pominięty upsert.
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'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.
Ten problem dotyczy ash_postgres: od 2.6.22 do 2.15.2.
