Summary

vantage6 is an open-source infrastructure for privacy preserving analysis. Prior to version 5.0.0, malicious algorithms can potentially access other algorithms input and output files. Version 5.0.0 fixes the issue. As a workaround, verify and restrict the algorithm containers that are allowed to run on the node.
