Background
vantage6 is an open-source privacy-preserving federated learning infrastructure. It provides a platform for collaborative data analysis while ensuring data privacy. The package allows users to create collaborations and perform tasks within those collaborations. It offers various functionalities for secure and efficient federated learning.
Vulnerability Detail
The vulnerability, identified as PYSEC-2023-201 (CVE-2023-41882), exists in vantage6 versions prior to 4.0.0. The endpoint '/api/collaboration/{id}/task' is responsible for retrieving tasks from a specific collaboration. However, the vulnerability allows unauthorized users to access the tasks without proper permission checks. While it verifies if the user has permission to view the collaboration, it fails to validate if the user has permission to view the tasks within that collaboration. This oversight can lead to unauthorized access to sensitive information and compromise the privacy and security of the federated learning process.
