## Technical details

This is a path traversal vulnerability (CWE-22) in the app installation archive extraction routine within Splunk SOAR. The vulnerable component fails to validate that extracted file paths remain within the intended temporary directory, allowing an attacker with app-install privileges to write files to arbitrary locations on the system. The attack requires network access and valid app-install privileges. Successful exploitation can result in arbitrary file writes, potentially enabling code execution or system integrity compromise. The vulnerability is fixed in Splunk SOAR 8.6.0 and later.
