Dag Authors, who normally should not be able to execute code in the webserver context could craft XCom payload causing the webserver to execute arbitrary code. Since Dag Authors are already highly trusted, severity of this issue is Low. Users are recommended to upgrade to Apache Airflow 3.2.0,...

A user with access to the DB could craft a database entry that would result in executing code on Triggerer - which gives anyone who have access to DB the same permissions as Dag Author. Since direct DB access is not usual and recommended for Airflow, the likelihood of it making any damage is low...

The authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop HITL and TaskInstance records: a logged-in Airflow user with read access to at least one DAG could retrieve HITL prompts including their request parameters and full TaskInstance details for DA...

JWT Tokens used by tasks were exposed in logs. This could allow UI users to act as Dag Authors. Users are advised to upgrade to Airflow version that contains fix. Users are recommended to upgrade to version 3.2.0, which fixes this issue...

BIT-AIRFLOW-2026-48891 Apache Airflow: /ui/dependencies scheduling graph leaks unreadable Dag identifiers via trigger/sensor dep.source/dep.target

A bug in Apache Airflow's /ui/dependencies scheduling graph endpoint applied the caller's readable-Dag filter to the top-level serialized Dag key but still emitted referenced Dag IDs through the dep.source and dep.target fields of trigger / sensor dependency entries. An authenticated UI user with...

BIT-AIRFLOW-2026-49296 Apache Airflow: Per-DAG read bypass discloses co-located DAGs' source via GET /api/v2/dagSources/{dag_id}

Before apache-airflow 3.3.0, a user authorized to read one Dag could disclose the source of other Dags co-located in the same source file. GET /api/v2/dagSources/dagid — and the equivalent Dag-source view in the UI — returned the entire source file without redacting Dags the caller was not...

PYSEC-2026-1135 Apache Airflow has a command injection vulnerability in "example_dag_decorator"

An example dag exampledagdecorator had non-validated parameter that allowed the UI user to redirect the example to a malicious server and execute code on worker. This however required that the example dags are enabled in production not default or the example dag code copied to build your own...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data in the BaseSerialization.deserialize process. An attacker can execute arbitrary code on the API Server or Scheduler by embedding a malicious trigger into a serialized DAG, which is then deserialized and...

Authorization Bypass Through User-Controlled Key

Overview Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key via the GET /api/v2/dagSources/dagid endpoint, which returns the entire source file containing multiple DAGs without redacting those the user is not authorized to access. An attacker can...

GHSA-4FH7-7JX4-8F6C apache-airflow DAG source authorization bypass exposes co-located DAG source

Apache Airflow allows code execution through unsafe serialized DAG deserialization

A bug in BaseSerialization.deserialize allowed unrestricted importstring of attacker-controlled class paths when the Scheduler / API Server loaded a serialized DAG: a DAG author could embed a malicious trigger into a DAG to gain remote code execution on the API Server / Scheduler process, crossin...
