CVE-2018-9159 is a path-traversal flaw in the Spark Java web framework before version 2.7.2. Spark's static-file handling permitted multiple representations of absolute or relative pathnames, including file-scheme URIs and directory-traversal sequences, to bypass intended static-resource path restrictions and disclose unintended files. This issue affects Spark Framework and is unrelated to Ignite Realtime Spark.
