Background
Apache Airflow is an open-source platform used for programmatically authoring, scheduling, and monitoring workflows. It provides a rich set of tools and features for managing Directed Acyclic Graphs (DAGs) that represent complex workflows. The platform allows users to define tasks, dependencies, and execution logic, making it easier to orchestrate data pipelines and automate data processing tasks. However, a security vulnerability has been identified in Apache Airflow versions prior to 2.7.2.
Vulnerability Detail
The vulnerability in Apache Airflow allows an authenticated user with limited access to some DAGs to exploit a flaw and gain unauthorized write access to various DAG resources. By crafting a specific request, the user can bypass their restricted access and gain write privileges for DAGs they should not have control over. This vulnerability enables the user to clear DAGs that they shouldn't, potentially disrupting critical workflows and causing data integrity issues.
