Horizon Alert
Summary of the vulnerability and why it matters
This advisory describes a security vulnerability in Apache DolphinScheduler that could allow unauthorized access to sensitive system information. The issue stems from a missing authorization check in the DataSource API, potentially exposing metadata related to data sources.
- Unauthorized access to system data.
- Potential for broad impact on data source information.
- Confirm relevance and exposure within your environment.
Attack Path
How an attacker could exploit the issue
An attacker could exploit this vulnerability by accessing the DataSource API without proper authorization. This missing authorization check allows an unauthenticated user to disclose sensitive metadata about data sources, potentially leading to further compromise of the system.
- No authentication needed for attack.
- Access the DataSource API.
- Arbitrary metadata disclosure risk.
