{"id":"CVE-2026-68871","aliases":["GHSA-qmrf-jrpr-rjx6","PYSEC-2026-3715"],"url":"https://o3.security/vulnerability/CVE-2026-68871","summary":"Apache Airflow Yandex provider: 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.","published":"2026-08-10T18:18:20.026Z","modified":"2026-10-21T02:59:04.441781856Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"apache-airflow-providers-yandex","fixedVersion":"4.5.1"}],"fix":{"url":"https://github.com/apache/airflow/pull/70877","label":"apache/airflow#70877"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/08/10/5"},{"type":"WEB","url":"https://pypi.python.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68871.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/jlj9tv085txk4t0j029mvh43mz89o63c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68871"},{"type":"FIX","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T02:59:04.441781856Z"}}
