{"id":"CVE-2026-42526","state":"PUBLISHED","title":"Apache Airflow Amazon provider: Prevent unauthorized access to team-scoped secrets in AWS Secrets Manager and SSM Parameter Store backends","description":"In the AWS Secrets Manager and SSM Parameter Store secrets backends of `apache-airflow-providers-amazon` prior to 9.28.0, the team-scoping logic could resolve a `conn_id` containing a `/` (e.g. `\"my_team/conn\"`) to the same path as another team's team-scoped secret when the caller had no team context. A privileged caller without team context could therefore retrieve another team's secret by crafting a colliding `conn_id`. Fixed in 9.28.0 by switching the team-scope separator to `--` and rejecting team-shaped `conn_id`s when team context is absent. Affects the experimental multi-tenant teams feature only. Users are recommended to upgrade to `apache-airflow-providers-amazon` 9.28.0, which fixes the issue.","publishedAt":"2026-05-19T19:17:51.565Z","updatedAt":"2026-05-19T19:53:24.129Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"CISA-ADP"},"assigner":"apache","products":["Apache Software Foundation Apache Airflow Amazon provider"],"affected":[{"vendor":"Apache Software Foundation","product":"Apache Airflow Amazon provider","packageName":"apache-airflow-providers-amazon","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"9.28.0","versionType":"semver"}],"collectionURL":"https://pypi.python.org"}],"references":["https://github.com/apache/airflow/pull/65703","https://lists.apache.org/thread/0092sz5g520d3qqjb01wd61myqlgjtyn","http://www.openwall.com/lists/oss-security/2026/05/19/36"],"weaknesses":["CWE-863"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/42xxx/CVE-2026-42526.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-42526","state":"PUBLISHED","datePublished":"2026-05-19T19:17:51.565Z","dateUpdated":"2026-05-19T19:53:24.129Z","assignerShortName":"apache","assignerOrgId":"f0158376-9dc2-43b6-827c-5f631a4d8d09","dateReserved":"2026-04-28T10:28:10.377Z"},"containers":{"cna":{"title":"Apache Airflow Amazon provider: Prevent unauthorized access to team-scoped secrets in AWS Secrets Manager and SSM Parameter Store backends","descriptions":[{"lang":"en","value":"In the AWS Secrets Manager and SSM Parameter Store secrets backends of `apache-airflow-providers-amazon` prior to 9.28.0, the team-scoping logic could resolve a `conn_id` containing a `/` (e.g. `\"my_team/conn\"`) to the same path as another team's team-scoped secret when the caller had no team context.
