# Security digest: November 20, 2025

2 critical advisories.

## Take stock

- npm: 2 critical advisories ( @hpke/core , md-to-pdf ). 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.

## Known exploited (CISA KEV)
