EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.8 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 64% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

vantage6 is a framework to manage and deploy privacy enhancing technologies like Federated Learning (FL) and Multi-Party Computation (MPC). In affected versions a node does not check if an image is allowed to run if a parent_id is set. A malicious party that breaches the server may modify it to set a fake parent_id and send a task of a non-whitelisted algorithm. The node will then execute it because the parent_id that is set prevents checks from being run. This impacts all servers that are breached by an expert user. This vulnerability has been patched in version 4.1.2. All users are advised to upgrade. There are no known workarounds for this vulnerability.
