{"id":"CVE-2026-68871","state":"PUBLISHED","title":"Apache Airflow Yandex provider: yandex Lockbox backend: team-scope guard bypass resolves another team's Connection or Variable","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.","publishedAt":"2026-08-10T18:18:20.026Z","updatedAt":"2026-09-16T14:56:26.393Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"CISA-ADP"},"assigner":"apache","products":["Apache Software Foundation Apache Airflow Yandex provider"],"affected":[{"vendor":"Apache Software Foundation","product":"Apache Airflow Yandex provider","packageName":"apache-airflow-providers-yandex","packageURL":"pkg:pypi/apache-airflow-providers-yandex","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"4.5.1","versionType":"semver"}],"collectionURL":"https://pypi.python.org"}],"references":["https://github.com/apache/airflow/pull/70877","https://lists.apache.org/thread/jlj9tv085txk4t0j029mvh43mz89o63c","http://www.openwall.com/lists/oss-security/2026/08/10/5"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/68xxx/CVE-2026-68871.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-68871","state":"PUBLISHED","datePublished":"2026-08-10T18:18:20.026Z","dateUpdated":"2026-09-16T14:56:26.393Z","assignerShortName":"apache","assignerOrgId":"f0158376-9dc2-43b6-827c-5f631a4d8d09","dateReserved":"2026-07-31T19:39:38.817Z"},"containers":{"cna":{"title":"Apache Airflow Yandex provider: yandex Lockbox backend: team-scope guard bypass resolves another team's Connection or Variable","descriptions":[{"lang":"en","value":"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.
