# Security digest: February 27, 2026

3 critical advisories.

## Take stock

- Go: 2 critical advisories ( code.vikunja.io/api , vitess.io/vitess ). Check with govulncheck ./... .
- PyPI: 1 critical advisory ( langflow ). Check with pip-audit (or: pip show <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.
