CVE-2026-76358
Path Traversal through App Installation Tar Extraction in Splunk SOAR
Description
In Splunk SOAR versions below 8.6.0, a user with app-install privileges could use path traversal during app installation to write files outside the intended temporary directory. The vulnerability is a path traversal in the archive extraction routine, which does not validate that extracted file paths stay within the intended destination directory.
