# Security digest: January 16, 2026

4 critical advisories.

## Take stock

- PyPI: 2 critical advisories ( crawl4ai , Crawl4AI ). Check with pip-audit (or: pip show <package>) .
- crates.io (Rust): 1 critical advisory ( deno ). Check with cargo audit .
- npm: 1 critical advisory ( @mcpjam/inspector ). 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)

None.
