Authorization Flaw in apache-airflow-providers-amazon (CVE-2026-42526)
Summary
Vulnerability in apache-airflow-providers-amazon (CVE-2026-42526). Confidential information can be exposed externally. Exploitable via conn_id. Mitigation: upgrade to 9.28.0 or later.
Original description
The description as published by the 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_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.
