## Description

In Splunk Enterprise versions below 10.4.1, 10.2.5, 10.0.8, 9.4.13, and 9.3.14, and Splunk Cloud Platform versions below 10.5.2605.0, 10.4.2604.6, 10.2.2510.18, and 10.1.2507.24, a user who holds a role that contains the \`edit\_local\_apps\` and \`install\_apps\` capabilities could cause a legitimate app installation to write files outside the intended app directory, into \`$SPLUNK\_HOME/etc/\` and its subdirectories.\<br\>\<br\>The vulnerability is caused by a path traversal in the app installation workflow, which does not restrict the installation path to the intended app directory.
