CVE-2026-68872 in Airflow
Summary
by MITRE • 08/10/2026
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.

Analysis

This vulnerability affects Apache Airflow deployments operating in multi-team mode with AWS Systems Manager Parameter Store or Secrets Manager backends in the Amazon provider. The flaw stems from improper access control implementation where the system fails to properly enforce team boundaries during credential resolution. When a team-scoped lookup fails, the system incorrectly falls back to a team-agnostic lookup mechanism that can resolve secrets belonging to other teams, creating a critical cross-team data leakage scenario.
The technical implementation issue occurs in the connection and variable resolution logic within Airflow's Amazon provider component. Specifically, when processing team-scoped identifiers, the system does not properly validate whether an identifier belongs to the requesting team's namespace or could potentially reference another team's resources. This creates a privilege escalation path where malicious actors can enumerate and access secrets from other teams by crafting identifiers that match target team namespaces.
The operational impact of this vulnerability is severe in multi-tenant Airflow deployments where isolation between teams is critical for security. Attackers can exploit this weakness to obtain full credentials including access keys, passwords, and other sensitive information belonging to different teams without requiring any special permissions or unusual configuration beyond enabling multi-team mode. This essentially breaks the fundamental security boundary that multi-team deployments are designed to maintain.
The vulnerability relates to CWE-284 Access Control Issues, specifically demonstrating improper access control in a multi-tenant environment where resource isolation is compromised. From an ATT&CK perspective, this maps to privilege escalation techniques using credential access and lateral movement through cross-team resource enumeration. The attack vector requires minimal prerequisites since it only needs access to the Airflow system with multi-team mode enabled.
Organizations should immediately upgrade to apache-airflow-providers-amazon version 9.34.0 or later to address this issue. The fix implements proper validation that prevents team-agnostic fallback for identifiers that could name a team namespace, ensuring that only appropriately scoped resources are accessible. Additionally, administrators should review existing team configurations and implement monitoring for unauthorized access patterns to detect potential exploitation attempts before they occur.
