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.\n\n## Affected\n\n- `apache-airflow-providers-apache-yandex < 4.5.1`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `apache-airflow-providers-apache-yandex 4.5.1`\n\n## Package advisory (CVE-2026-68871)\n\nAffected packages:\n\n- `apache-airflow-providers-yandex < 4.5.1`\n\nPatched in:\n\n- `apache-airflow-providers-yandex 4.5.1`\n\nSource: https://osv.dev/vulnerability/PYSEC-2026-3715","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
