CVE-2026-68871 Apache Software Foundation CVE debrief

CVE-2026-68871 debrief: Apache Airflow Yandex provider vulnerability allows unauthorized secret access in multi-team mode, enabling a caller in one team to resolve secrets belonging to another team. This occurs when the Yandex Lockbox secrets backend resolves team-scoped Connection or Variable ids through team-agnostic lookup if the team-scoped lookup misses. The vulnerability requires enabling multi-team mode and using this backend, with no unusual configuration needed beyond that. Users should upgrade to apache-airflow-providers-yandex 4.5.1 or later to refuse the team-agnostic fall-through for ids that could name a team namespace.

Who should care

Defenders responsible for Apache Airflow deployments in multi-team mode with the Yandex provider should assess exposure and prioritize upgrading to apache-airflow-providers-yandex 4.5.1 or later.

Why it matters

CVE-2026-68871 allows unauthorized secret access in Apache Airflow's Yandex provider in multi-team mode, requiring defenders to assess exposure and prioritize remediation.

  • Potential unauthorized access to sensitive secrets
  • Increased risk of credential exposure
  • Need for verification of current configurations and access controls
  • Priority for upgrading to patched version

Technical summary

The Yandex Lockbox secrets backend in Apache Airflow's Yandex provider has a vulnerability allowing unauthorized secret access 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. This occurs when the team-scoped lookup misses, and the backend falls back to team-agnostic lookup. The vulnerability does not require unusual configuration beyond enabling multi-team mode and using this backend. The issue is addressed in apache-airflow-providers-yandex 4.5.1 or later.

Defensive priority

Defenders should prioritize upgrading to apache-airflow-providers-yandex 4.5.1 or later to prevent unauthorized secret access in multi-team mode.

Recommended defensive actions

  • Upgrade to apache-airflow-providers-yandex 4.5.1 or later
  • Review and restrict access to sensitive secrets in multi-team mode
  • Monitor for potential unauthorized access attempts
  • Verify current configurations and access controls for multi-team mode deployments
  • Perform an inventory of assets using the affected Yandex provider
  • Track exceptions and retest remediated assets
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
