CVE-2026-8326Network attack vector

Root code execution via drive-redirection traversal

Published May 29, 2026 · Updated May 29, 2026

Path traversal in SparkView before build 1127 allows remote attackers to read and write arbitrary files as root through RDP drive redirection. The component fails to keep paths received from a malicious RDP server within the intended directory before performing file operations. Exploitation requires the gateway to connect to that server; crafted file writes can place executable content and yield root code execution.
