Background
vantage6 is an open-source privacy-preserving federated learning infrastructure. It provides a platform for collaborative machine learning tasks while ensuring data privacy. The package allows multiple organizations to share and analyze data without exposing sensitive information. However, a vulnerability has been discovered in versions prior to 4.0.0 that could lead to privacy leakage.
Vulnerability Detail
The vulnerability in vantage6 arises when a collaboration is deleted. In previous versions, the linked resources, such as tasks from the deleted collaboration, were not properly removed. This oversight could potentially allow authenticated users in a new collaboration with the same ID to access results from the deleted collaboration. Although the likelihood of this side-effect is low, it poses a risk to data privacy. The issue has been addressed in version 4.0.0, which includes a patch to ensure proper deletion of linked resources.
