CVE-2026-56796

Privilege escalation via link-followed file access

Published Aug 19, 2026 · Updated Aug 19, 2026

Link following in Dell Command Update before 5.7.1 allows local users to gain elevated privileges via crafted filesystem links. Dell and NVD identify CWE-59, but the published records do not name the specific DCU component or file operation that resolves an attacker-influenced link before accessing the target. Reachability requires low-privileged local access on a system running the vulnerable release, and published material describes privilege escalation rather than remote code execution or service interruption.
