Background
Apache Airflow is an open-source platform designed to programmatically author, schedule, and monitor workflows. It allows users to define workflows as Directed Acyclic Graphs (DAGs) and provides a rich user interface to visualize and manage these workflows. However, a vulnerability has been identified that compromises the security of DAG import error logs, potentially exposing sensitive information to unauthorized users.
Vulnerability Detail
The vulnerability stems from a flaw in the Apache Airflow UI that fails to properly filter import errors based on DAG permissions. This allows authenticated users to access import errors for DAGs they do not have permission to view. The exposed logs may contain sensitive information such as file paths, code snippets, and stack traces, which can reveal the internal workings of restricted DAGs. This information disclosure could lead to unauthorized access to sensitive data and compromise the integrity of the workflows.
