Apache Airflow 3.1.3

Airflow ships security and reliability fixes including refined API server secret context handling and the removal of the insecure dagReports endpoint. Expect safer cross-context secret access, faster API server performance, and enhanced hook support in log handlers without plugin changes.
Fix Connection & Variable access in API server contexts (plugins, log handlers)(#56583)

Previously, hooks used in API server contexts (plugins, middlewares, log handlers) would fail with an
ImportError
for
SUPERVISOR_COMMS
, because
SUPERVISOR_COMMS
only exists in task runner child processes.
This has been fixed by implementing automatic context detection with three separate secrets backend chains:

Context Detection:

Client contexts (task runner in worker): Detected via
SUPERVISOR_COMMS
presence

Server contexts (API server, scheduler): Explicitly marked with
_AIRFLOW_PROCESS_CONTEXT=server
environment variable

Fallback contexts (supervisor, unknown contexts): Neither marker present, uses minimal safe chain

Backend Chains:

Client:
EnvironmentVariablesBackend
→
ExecutionAPISecretsBackend
(routes to Execution API via SUPERVISOR_COMMS)

Server:
EnvironmentVariablesBackend
→
MetastoreBackend
(direct database access)

Fallback:
EnvironmentVariablesBackend
only (+ external backends from config like AWS Secrets Manager, Vault)

The fallback chain is crucial for supervisor processes (worker-side, before task runner starts) which need to access
external secrets for remote logging setup but should not use
MetastoreBackend
(to maintain worker isolation).

Architecture Benefits:

Workers (supervisor + task runner) never use
MetastoreBackend
, maintaining strict isolation

External secrets backends (AWS Secrets Manager, Vault, etc.) work in all three contexts

Supervisor falls back to Execution API client for connections not found in external backends

API server and scheduler have direct database access for optimal performance

Impact:

Hooks like
GCSHook
,
S3Hook
now work correctly in log handlers and plugins

No code changes required for existing plugins or hooks

Workers remain isolated from direct database access (network-level DB blocking fully supported)

External secrets work everywhere (workers, supervisor, API server)

Robust handling of unknown contexts with safe minimal chain

Remove insecure dag reports API endpoint that executed user code in API server (#56609)

Remove insecure dag reports API endpoint that executed user code in API server (#56609)

The
/api/v2/dagReports
endpoint has been removed because it loaded user DAG files directly in the API server process,
violating Airflow's security architecture. This endpoint was not used in the UI and had no known consumers.
Use the
airflow dags report
CLI command instead for DAG loading reports.
