Microsoft Windows, ConnectWise ScreenConnect. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2026-05-12. - Go: 1 critical advisory ( github.com/gravitl/netmaker ). Check with govulncheck ./... . - PyPI: 1 critical advisory ( nvflare ). Check with pip-audit (or: pip show ) . - None of it touches your stack? Then there is nothing to do today.
