CVE-2026-68872 Apache Software Foundation CVE debrief

Who should care

Defenders managing Apache Airflow deployments in multi-team mode with AWS Systems Manager Parameter Store and Secrets Manager backends should assess exposure and prioritize upgrading to apache-airflow-providers-amazon 9.34.0 or later.

Why it matters

CVE-2026-68872 allows unauthorized secret resolution across teams in Apache Airflow's Amazon provider when using AWS Systems Manager Parameter Store and Secrets Manager backends in multi-team mode. Defenders should prioritize upgrading and restrict access to prevent exploitation.

• Verify and restrict access to AWS Systems Manager Parameter Store and Secrets Manager backends
• Upgrade to apache-airflow-providers-amazon 9.34.0 or later to prevent unauthorized secret resolution
• Monitor for suspicious activity in multi-team mode

Technical summary

The AWS Systems Manager Parameter Store and Secrets Manager backends in Apache Airflow's Amazon provider resolve a team-scoped Connection or Variable id through the team-agnostic lookup when the team-scoped lookup missed. This allows a caller in one team to resolve a secret belonging to another team by supplying an id that spells out that team's namespace, potentially leading to unauthorized credential exposure. The vulnerability requires multi-team mode and the use of either backend. 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, preventing unauthorized secret resolution across teams.

Defensive priority

Defenders should prioritize upgrading to apache-airflow-providers-amazon 9.34.0 or later to prevent unauthorized secret resolution across teams.

Recommended defensive actions

• Upgrade to apache-airflow-providers-amazon 9.34.0 or later to prevent unauthorized secret resolution across teams
• Review and restrict access to AWS Systems Manager Parameter Store and Secrets Manager backends
• Monitor for suspicious activity in multi-team mode
• Verify and restrict access to AWS Systems Manager Parameter Store and Secrets Manager backends
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The vulnerability exists in Apache Airflow's Amazon provider when using AWS Systems Manager Parameter Store and Secrets Manager backends in multi-team mode. A caller in one team can resolve a secret belonging to another team by supplying an id that spells out that team's namespace.
