      "value": "Apache Airflow's environment-variable secrets backend resolved a team-scoped Connection or Variable from the wrong team's scope. The guard meant to prevent this only ran when no team scope was supplied, and its pattern could not match a team name containing an underscore, which team names are allowed to contain. When the guard did not apply, the lookup fell through to an unconditional global read that resolved the stored `AIRFLOW_CONN__<TEAM>___<ID>` variable regardless of which team asked. In multi-team mode an authenticated user of one team could therefore have `POST /api/v2/connections/test` resolve another team's Connection and authenticate outward with that team's credentials; the endpoint uses the credentials rather than returning them. Exploitation requires `[core] multi_team` enabled, `[core] test_connection` set to `Enabled` (it ships `Disabled`), team-scoped secrets provisioned as environment variables in the API-server process, and knowledge of the encoded identifier. Redirecting the test at an attacker-controlled host is separately blocked. Users are advised to upgrade to apache-airflow 3.3.1 or later."

      "value": "El backend de secretos de variables de entorno de Apache Airflow resolvió una Conexión o Variable con ámbito de equipo del ámbito de equipo incorrecto. La protección destinada a evitar esto solo se ejecutaba cuyo no se proporcionaba ningún ámbito de equipo, y su patrón no podía coincidir con un nombre de equipo que contuviera un guion bajo, que los nombres de equipo pueden contener. Cuyo la protección no se aplicaba, la búsqueda recurría a una lectura global incondicional que resolvía la variable almacenada ’AIRFLOW_CONN__[TEAM]___[ID]’ independientemente de qué equipo la solicitara. En modo multi-equipo, un usuario autenticado de un equipo podría, por lo tanto, hacer que ’POST /api/v2/connections/test’ resolviera la Conexión de otro equipo y autenticarse externamente con las credenciales de ese equipo; el endpoint utiliza las credenciales en lugar de devolverlas. La explotación requiere ’[core] multi_team’ habilitado, ’[core] test_connection’ configurado como ’Enabled’ (se distribuye ’Disabled’), secretos con ámbito de equipo aprovisionados como variables de entorno en el proceso del servidor-API, y conocimiento del identificador codificado. Redirigir la prueba a un host controlado por el atacante está bloqueado por separado. Se aconseja a los usuarios actualizar a apache-airflow 3.3.1 o posterior."
