+  <name>Apache Spark Unauthenticated Command Injection</name>

+  <description>The Apache Spark UI offers the possibility to enable ACLs via the configuration
+    option spark.acls.enable.
+    With an authentication filter, this checks whether a user has access permissions to view or
+    modify the application.
+    If ACLs are enabled, a code path in HttpSecurityFilter can allow someone to perform
+    impersonation by providing an arbitrary user name.
+    A malicious user might then be able to reach a permission check function that will ultimately
+    build a Unix shell command based on their input, and execute it.
+    This will result in arbitrary shell command execution as the user Spark is currently running as.
+    This affects Apache Spark versions 3.0.3 and earlier, versions 3.1.1 to 3.1.2, and versions
+    3.2.0 to 3.2.1.</description>
