## Affected

- Splunk Splunk SOAR: from 8.6, fixed in 8.6.0

## Description

In Splunk SOAR versions below 8.6.0, a user who holds the OnPrem Broker role could write files outside the intended Automation Broker log directory. The vulnerability is possible because Automation Broker log uploads accept crafted filename input before writing log files.
