Joe DiPol commented on KAFKA-15138:
-----------------------------------
The CVEs on these compression libraries continue:
[ERROR] lz4-java-1.10.1.jar (pkg:maven/at.yawk.lz4/[email protected]):

The snappy project hasn't had a commit by a human in almost a year -- despite
multiple CVEs.
We know the situation with Lz4-java
Yet the kafka client still insists on requiring them as transitive
dependencies. Can you please make these optional?

>
> Key: KAFKA-15138
> URL: https://issues.apache.org/jira/browse/KAFKA-15138
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 3.4.0
> Reporter: Joe DiPol
> Priority: Major
>
> If you look at
> [https://repo1.maven.org/maven2/org/apache/kafka/kafka-clients/3.4.0/kafka-clients-3.4.0.pom]
> You see that the dependencies for the compression libraries (like lz4-java)
> do NOT have "{{{}<optional>true</optional>{}}}". That means that these
> libraries are transitive dependencies which will be pulled (and potentially
> security scanned) for any project that uses kafka-clients.
> This is not correct. These compression libraries are optional and should not
> be transitive dependencies of kafka-clients. Therefore the above pom should
> state {{optional}} like:
> {{
> <dependency>
> <groupId>org.lz4</groupId>
> <artifactId>lz4-java</artifactId>
> <version>1.8.0</version>
> <scope>runtime</scope>
> <optional>true</optional>
> </dependency>
> }}
