Arbitrary file read via injected SQLAlchemy scheme
Published Jun 27, 2023 · Updated Oct 7, 2024
Improper input validation in Apache Airflow ODBC and MSSQL Providers before 4.0.0 and 3.4.1 allows remote authenticated users to read files. The OdbcHook and MsSqlHook sqlalchemy_scheme properties accept a connection-extra value containing colon or slash characters and insert it into the SQLAlchemy engine URI. Exploitation requires DAG code to call get_sqlalchemy_connection and access to modify the corresponding Airflow connection resource; the result is bounded to files readable by the Airflow process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
