Summary from the TLDR InfoSec newsletter

A critical path traversal flaw in Dell System Update (CVE-2026-86360) allowed unauthenticated remote attackers to execute code as root on PowerEdge servers using the DSU deployment tool. Dell's advisory also addressed four other high-severity DSU vulnerabilities: two that enable remote code execution (CVE-2026-63697 and CVE-2026-71168) and two that enable privilege escalation (CVE-2026-86361 and CVE-2026-86362). None have been reported as exploited so far. Admins should upgrade to DSU 2.3.0.0 or later.
