{"schema_version": "1.6.1", "id": "CVE-2026-68871", "summary": "yandex Lockbox backend: team-scope guard bypass resolves another team's Connection or Variable", "details": "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.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "0"}, {"fixed": "4.5.1"}]}]}], "references": [{"type": "WEB", "url": "https://github.com/apache/airflow/pull/70877"}, {"type": "WEB", "url": "https://lists.apache.org/thread/jlj9tv085txk4t0j029mvh43mz89o63c"}]}
