# Security digest: December 13, 2023

3 critical advisories.

## Take stock

- Go: 1 critical advisory ( github.com/sap/cloud-security-client-go ). Check with govulncheck ./... .
- PyPI: 1 critical advisory ( sap-xssec ). Check with pip-audit (or: pip show <package>) .
- Maven: 1 critical advisory ( com.sap.cloud.security:java-security , com.sap.cloud.security:spring-security , com.sap.cloud.security.xsuaa:spring-xsuaa ). Check with mvn dependency:tree -Dincludes=<groupId>:<artifactId> .
- 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.
