Take stock

  • Do you run any of these? F5 BIG-IP. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2026-03-30.
  • npm: 3 critical advisories (openclaw, handlebars). Check with npm audit (or: npm ls <package>).
  • Go: 2 critical advisories (github.com/lxc/incus/v6, github.com/lxc/incus). Check with govulncheck ./....
  • crates.io (Rust): 1 critical advisory (zebrad, zebra-chain). Check with cargo audit.
  • PyPI: 1 critical advisory (pyload-ng). Check with pip-audit (or: pip show <package>).
  • None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.
