Privilege Escalation in vantage6 Prior to 5.0.0

Executive Summary

The vulnerability in vantage6, an open-source infrastructure for privacy preserving analysis, exists in versions prior to 5.0.0. It allows malicious algorithms to potentially access the input and output files of other algorithms running on the same node.

This means that unauthorized algorithms could read sensitive data processed by other algorithms, compromising data privacy.

Version 5.0.0 of vantage6 fixes this issue. As a workaround before upgrading, it is recommended to verify and restrict which algorithm containers are allowed to run on the node.
