# Security digest: March 11, 2026

1 known exploited (cisa kev) addition and 2 critical advisories.

## Take stock

- Do you run any of these? n8n n8n. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2026-03-25.
- GitHub Actions: 1 critical advisory ( xygeni/xygeni-action ). Check with grep -rn 'uses: <owner>/<action>' .github/workflows .
- Go: 1 critical advisory ( github.com/cosmos/evm ). Check with govulncheck ./... .
- 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)

- [CVE-2025-68613](https://erroneo.us/security/cve/CVE-2025-68613/index.md) n8n n8n: n8n Improper Control of Dynamically-Managed Code Resources Vulnerability (CISA due 2026-03-25)

## Critical advisories
