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.

Other vulnerabilities in apache-airflow-providers-amazon

CVE-2026-86467High
In Apache Airflow Amazon provider, the AWS auth manager's SAML login flow does not bind the authentication response to the browser that began it. The login handler discards the AuthnRequest ID and the callback validates the assertion without requiring a matching InResponseTo, allowing an unauthenticated attacker to silently log a victim into the attacker's Airflow account.

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.
