Hi,

We are going through [Security risk in netty-all-4.1.58.Final.jar used by Cassandra - Stack Overflow](https://stackoverflow.com/questions/75228395/security-risk-in-netty-all-4-1-58-final-jar-used-by-cassandra)

I know MySQL is not in scope, just wanted to ensure if I am right in this case. Please confirm if MySQL or even any clients are in scope for this vulnerability.

Thank you

That very stackexchange link has the answer:

> The issues with Netty has already been identified, assessed as “not applicable”, and added to the [suppression list](https://github.com/apache/cassandra/blob/cassandra-4.0/.build/dependency-check-suppressions.xml#L74-L84) ([CASSANDRA-17368](https://issues.apache.org/jira/browse/CASSANDRA-17368)).

This vulnerability seems specific to Java/Netty and not applicable to MySQL. If you can find a CVE related to MySQL, we can explore further.

Hi Matthew,

From what I read, possibly MariaDB client probably uses Netty (Not confident though).  
Thanks for confirming it is not applicable for MySQL (percona).

Thank you
