# Security digest: March 29, 2026

5 critical advisories.

## Take stock

- npm: 2 critical advisories ( @mikro-orm/core , mppx ). Check with npm audit (or: npm ls <package>) .
- PyPI: 1 critical advisory ( mlflow ). Check with pip-audit (or: pip show <package>) .
- GitHub Actions: 1 critical advisory ( njzjz/wenxian ). Check with grep -rn 'uses: <owner>/<action>' .github/workflows .
- crates.io (Rust): 1 critical advisory ( mpp ). Check with cargo audit .
- 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.
