CVE-2026-21420

Local privilege escalation via uncontrolled search path

Published Feb 23, 2026 · Updated Feb 23, 2026

Uncontrolled search path handling in Dell Repository Manager before 3.4.8 allows local users to execute code with elevated privileges. Dell has not disclosed the affected executable, library lookup, or the untrusted path element that it searches before a trusted location. Exploitation requires low-privilege local access and user interaction, and successful code execution grants high-privilege control over the host.
