What is CVE-2018-1296?

A security issue exists in Apache Hadoop's HDFS that allows unauthorized exposure of extended attribute key/value pairs during the listXAttrs operation. This flaw arises because the system verifies only path-level search access instead of enforcing the necessary path-level read permissions for the underlying data, leading to potential unauthorized data exposure.

Affected Version(s)

Apache Hadoop Apache Hadoop 3.0.0-alpha1 to 3.0.0, 2.9.0, 2.8.0 to 2.8.3, 2.5.0 to 2.7.5
