# Security digest: December 4, 2025

1 critical advisory.

## Take stock

- Maven: 1 critical advisory ( org.apache.tika:tika-core , org.apache.tika:tika-parsers , org.apache.tika:tika-parser-pdf-module ). 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.
