{"id":"GHSA-qmrf-jrpr-rjx6","summary":"Apache Airflow Yandex Lockbox backend allows cross-team secret disclosure","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.","aliases":["CVE-2026-68871","PYSEC-2026-3715"],"modified":"2026-10-02T23:40:51.844382389Z","published":"2026-08-10T21:32:02Z","database_specific":{"github_reviewed_at":"2026-10-02T23:11:39Z","nvd_published_at":"2026-08-10T19:17:30Z","cwe_ids":["CWE-639"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68871"},{"type":"WEB","url":"https://github.com/apache/airflow/pull/70877"},{"type":"WEB","url":"https://github.com/apache/airflow/commit/0d877a1a7680d779d3e8d24cf1bd50b0af1fc8d7"},{"type":"PACKAGE","url":"https://github.com/apache/airflow"},{"type":"WEB","url":"https://github.com/apache/airflow/releases/tag/providers-yandex/4.5.1"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/apache-airflow-providers-yandex/PYSEC-2026-3715.yaml"},{"type":"WEB","url":"https://lists.apache.org/thread/jlj9tv085txk4t0j029mvh43mz89o63c"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/08/10/5"}],"affected":[{"package":{"name":"apache-airflow-providers-yandex","ecosystem":"PyPI","purl":"pkg:pypi/apache-airflow-providers-yandex"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.5.1"}]}],"versions":["1.0.0","1.0.0b1","1.0.0b2","1.0.0rc1","1.0.1","1.0.1rc1","2.0.0","2.0.0rc1","2.0.0rc2","2.1.0","2.1.0rc1","2.2.0","2.2.0rc1","2.2.1","2.2.1rc1","2.2.2","2.2.2rc1","2.2.3","2.2.3rc1","3.0.0","3.0.0rc1","3.0.0rc2","3.1.0","3.1.0rc1","3.1.0rc2","3.1.0rc3","3.10.0","3.10.0rc2","3.11.0","3.11.0rc1","3.11.1","3.11.1rc1","3.11.2","3.11.2rc1","3.12.0","3.12.0rc1","3.2.0","3.2.0rc1","3.2.0rc2","3.2.0rc3","3.3.0","3.3.0rc1","3.4.0","3.4.0rc1","3.5.0","3.5.0rc1","3.6.0","3.6.0rc1","3.7.0","3.7.0rc1","3.7.1","3.7.1rc1","3.8.0","3.8.0rc1","3.8.0rc2","3.9.0","3.9.0rc1","3.9.1rc1","4.0.0","4.0.0rc1","4.0.0rc2","4.0.1","4.0.1rc1","4.0.2","4.0.2rc1","4.0.3","4.0.3rc1","4.1.0","4.1.0rc1","4.1.1","4.1.1rc1","4.2.0","4.2.0rc1","4.2.1","4.2.1rc1","4.3.0","4.3.0rc1","4.3.1","4.3.1rc1","4.3.2","4.3.2rc1","4.3.3","4.3.3rc1","4.4.0","4.4.0rc1","4.4.1","4.4.1rc1","4.4.2","4.4.2rc1","4.5.0","4.5.0rc1","4.5.1rc1","4.5.1rc2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-qmrf-jrpr-rjx6/GHSA-qmrf-jrpr-rjx6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
