Description

The Yandex Lockbox secrets backend in Apache Airflow's Yandex 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 this 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 this backend. Users are advised to upgrade to apache-airflow-providers-yandex 4.5.1 or later, which refuses the team-agnostic fall-through for an id that could name a team namespace.
