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 ids 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.
