Arnout Engelen commented on CASSANDRA-18150:
--------------------------------------------
The change in
[https://github.com/apache/cassandra/commit/e7f55ab8c3bd6bac4c87354afec231d7237c35b8]
might not be effective: it seems that, confusingly, while the
'CustomConstructor' class extends the 'SafeConstructor' one, not every 'Custom'
constructor is actually necessarily 'Safe' :(. Should we reopen this issue or
create a new one?
> Prefer snakeyaml's SafeConstructor over Constructor

> CVE-2022-1471 allows RCE through the Constructor class. While this isn't a
> concern since yaml is only used for configuration, it is simple enough to
> switch to SafeConstructor and harden the server a little more.
