CVE-2022-42889: Keep Calm and Stop Saying "Text4Shell"
UPDATE 10/18/22: A previous version of this blog indicated that five JDK
versions (JDK 15+) were not impacted due to the exclusion of the Nashorn
JavaScript engine. However, an updated PoC
[http://twitter.com/pwntester/status/1582321752566161409]came out that uses the
JEXL engine as an exploit path. If JEXL is present, the code executes

can be leveraged.
