## Technical details

This is a path traversal vulnerability (CWE-22) in the Universal Forwarder credentials-package extraction workflow within Splunk SOAR versions below 8.6.0. The vulnerability exists because the archive extraction routine does not validate that extracted file paths remain within the intended destination directory before extraction. An authenticated user with the Administrator role can exploit this by crafting a malicious archive with path traversal sequences (e.g., "../") to write files to arbitrary locations on the system. No user interaction is required beyond the attacker having Administrator privileges. The fix is available in Splunk SOAR 8.6.0 and later.
