Summary
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 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_ids when team context is absent. Affects the experimental multi-tenant teams feature only.
Risk Assessment
Risk of unauthorized access to secrets of other teams in a multi-tenant environment. This could lead to leakage of confidential data.
Recommendation
Update apache-airflow-providers-amazon to version 9.28.0 or later. If using the multi-tenant teams feature, review the configuration.

Original NVD description (English source)
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.
