# Security digest: June 1, 2026

1 known exploited (cisa kev) addition and 4 critical advisories.

## Take stock

- Do you run any of these? Oracle WebLogic Server. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2026-06-04.
- PyPI: 2 critical advisories ( apache-airflow , praisonai-platform ). Check with pip-audit (or: pip show <package>) .
- npm: 2 critical advisories ( vitest , @vitest/browser ). 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.
