CVE-2022-40152 is a medium-severity flaw (CVSS 6.5) affecting xstream, woodstox. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Those using Woodstox to parse XML data may be vulnerable to Denial of Service attacks (DOS) if DTD support is enabled. If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow. This effect may support a denial of service attack.
