apache-airflow-providers-google is vulnerable to Path Traversal
81
High Risk
This Affects:
apache-airflow-providers-googleTL;DR
The Google provider operators GCSToSFTPOperator and GCSTimeSpanFileTransformOperator join Google Cloud Storage object names onto a destination filesystem path without normalizing them or checking containment. An object name that contains .. segments resolves outside the configured destination when a DAG run downloads it. A principal with write access to the source bucket can overwrite arbitrary files on the SFTP server or the Airflow worker host, which can lead to host compromise. The fix normalizes object names and rejects paths that escape the configured base directory.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you ingest from a Google Cloud Storage bucket writable by an untrusted principal using GCSToSFTPOperator or GCSTimeSpanFileTransformOperator.
