CVE-2023-47631: vantage6 Node accepts non-whitelisted algorithms from malicious server
Impact A node does not check if an image is allowed to run if a parentid is set. A malicious party that breaches the server may modify it to set a fake parentid and send a task of a non-whitelisted algorithm. The node will then execute it because the parentid that is set prevents checks from being run. Relevant node code here
This impacts all servers that are breached by an expert user
