CVE-2026-42526: CWE-863: Incorrect Authorization in Apache Software Foundation Apache Airflow Amazon provider
CVE-2026-42526 is a medium severity vulnerability in the Apache Airflow Amazon provider affecting versions prior to 9. 28. 0. It involves incorrect authorization in the AWS Secrets Manager and SSM Parameter Store secrets backends related to team-scoping logic. A privileged caller without team context could exploit a crafted connection ID containing a '/' to access another team's secrets. This issue impacts the experimental multi-tenant teams feature. The vulnerability is fixed in version 9. 28. 0 by changing the team-scope separator and rejecting certain connection IDs when team context is absent.
AI Analysis
Technical Summary
The vulnerability arises from flawed team-scoping logic in the AWS Secrets Manager and SSM Parameter Store backends of the apache-airflow-providers-amazon package before version 9.28.0. Specifically, a connection ID (conn_id) containing a '/' character could be resolved to the same path as another team's secret if the caller lacked a team context, allowing unauthorized secret retrieval. The fix in version 9.28.0 replaces the team-scope separator with '--' and rejects team-shaped conn_ids when no team context is present, mitigating the risk. This affects only the experimental multi-tenant teams feature.
Potential Impact
An attacker with privileged access but no team context could retrieve secrets belonging to other teams by exploiting the team-scoping logic flaw. This leads to unauthorized disclosure of sensitive secrets stored in AWS Secrets Manager or SSM Parameter Store via the Apache Airflow Amazon provider. The impact is confidentiality loss without affecting integrity or availability.
Mitigation Recommendations
A patch is available in apache-airflow-providers-amazon version 9.28.0 that fixes this vulnerability. Users of the experimental multi-tenant teams feature should upgrade to version 9.28.0 or later. Since this is a cloud-hosted service component, the vendor manages remediation for the cloud service; users should verify their provider version and update accordingly.
