5.4 MediumFix available

CVE-2018-8024 is a medium vulnerability (CVSS 5.4) in Apache Spark, published July 12, 2018. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 5.29%, the 92nd percentile. Fixed in org.apache.spark:spark-core_2.10 2.1.3.

In Apache Spark 2.1.0 to 2.1.2, 2.2.0 to 2.2.1, and 2.3.0, it's possible for a malicious user to construct a URL pointing to a Spark cluster's UI's job and stage info pages, and if a user can be tricked into accessing the URL, can be used to cause script to execute and expose information from the user's view of the Spark UI. While some browsers like recent versions of Chrome and Safari are able to block this type of attack, current versions of Firefox (and possibly others) do not.
