# Security digest: December 7, 2023

2 known exploited (cisa kev) additions and 1 critical advisory.

## Take stock

- Do you run any of these? Qlik Sense. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2023-12-28.
- Maven: 1 critical advisory ( org.apache.struts:struts2-core ). 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)

- [CVE-2023-41266](https://erroneo.us/security/cve/CVE-2023-41266/index.md) Qlik Sense: Qlik Sense Path Traversal Vulnerability (CISA due 2023-12-28)
