      "value": "In the AWS Secrets Manager and SSM Parameter Store secrets backends of `apache-airflow-providers-amazon` prior to 9.28.0, the team-scoping logic could resolve a `conn_id` containing a `/` (e.g. `\"my_team/conn\"`) to the same path as another team's team-scoped secret when the caller had no team context. A privileged caller without team context could therefore retrieve another team's secret by crafting a colliding `conn_id`. Fixed in 9.28.0 by switching the team-scope separator to `--` and rejecting team-shaped `conn_id`s when team context is absent. Affects the experimental multi-tenant teams feature only. Users are recommended to upgrade to `apache-airflow-providers-amazon` 9.28.0, which fixes the issue."

Un llamador privilegiado sin contexto de equipo podría, por lo tanto, recuperar el secreto de otro equipo al crear un 'conn_id' en colisión. Corregido en la versión 9.28.0 al cambiar el separador de alcance de equipo a  --  y rechazando los 'conn_id' con forma de equipo cuando el contexto de equipo está ausente. Afecta solo a la característica experimental de equipos multi-inquilino. Se recomienda a los usuarios actualizar a 'apache-airflow-providers-amazon' 9.28.0, que corrige el problema."
