{"schema_version": "1.6.1", "id": "CVE-2026-42526", "summary": "Prevent unauthorized access to team-scoped secrets in AWS Secrets Manager and SSM Parameter Store backends", "details": "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.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "0"}, {"fixed": "9.28.0"}]}]}], "references": [{"type": "WEB", "url": "https://github.com/apache/airflow/pull/65703"}, {"type": "WEB", "url": "https://lists.apache.org/thread/0092sz5g520d3qqjb01wd61myqlgjtyn"}]}
