Anyone running Ray clusters (self-managed, on Kubernetes/KubeRay or on cloud VMs) whose head node ports, especially the dashboard/Jobs port 8265, are reachable from the internet or other untrusted networks. - Do you run any of these? Microsoft SharePoint Server. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2024-04-16. - PyPI: 1 critical advisory ( Lektor ). Check with pip-audit (or: pip show ) . - None of it touches your stack? Then there is nothing to do today.
