CVE-2026-68872: Apache Airflow Amazon provider: amazon SSM / Secrets Manager backends: team-scope guard bypass resolves another team's Connection or Variable

Severity: medium (CVSS 6.5 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.6% probability of exploitation in the next 30 days

Weakness: CWE-639

Description

The AWS Systems Manager Parameter Store and Secrets Manager backends in Apache Airflow's Amazon provider resolved a team-scoped Connection or Variable id through the team-agnostic lookup when the team-scoped lookup missed. In a deployment running multi-team mode with either backend, a caller in one team could resolve a secret belonging to another team by supplying an id that spells out that team's namespace, obtaining its credentials in full. No unusual configuration is required beyond enabling multi-team mode and using one of these backends. Users are advised to upgrade to apache-airflow-providers-amazon 9.34.0 or later, which refuses the team-agnostic fall-through for an id that could name a team namespace.

Affected products

Apache Software Foundation Apache Airflow Amazon provider: before 9.34.0 — fixed in 9.34.0

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Airflow Amazon provider 9.34.0. Check the vendor advisory for mitigations.
