CVE-2022-41854:

Those using Snakeyaml to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stack overflow. This effect may support a denial of service attack.

Any fix?

Functionality is working as designed according to upstream: https://bitbucket.org/snakeyaml/snakeyaml/issues/569/cve-2022-41854-is-still-exploitable-on
