# Security digest: December 11, 2023

1 known exploited (cisa kev) addition and 1 critical advisory.

## Take stock

- Do you run any of these? Unitronics Vision PLC and HMI. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2023-12-18.
- npm: 1 critical advisory ( @sap/xssec ). 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)

- [CVE-2023-6448](https://erroneo.us/security/cve/CVE-2023-6448/index.md) Unitronics Vision PLC and HMI: Unitronics Vision PLC and HMI Insecure Default Password Vulnerability (CISA due 2023-12-18)

## Critical advisories

- [CVE-2023-49583](https://erroneo.us/security/cve/CVE-2023-49583/index.md) Escalation of privileges in @sap/xssec — npm @sap/xssec < 3.6.0 → 3.6.0
