# Security digest: November 3, 2026

1 known exploited (cisa kev) addition and 2 critical advisories.

## Take stock

- Do you run any of these? WordPress WordPress Core. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2026-11-06.
- npm: 2 critical advisories ( @enspirit/elo ). Check with npm audit (or: npm ls <package>) .
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.
