CVE-2025-26331

Local code execution via undisclosed command injection

Published Mar 7, 2025 · Updated Feb 26, 2026

Command injection in Dell ThinOS 2411 and earlier allows local users with low privileges to execute arbitrary code on the thin client. Dell has not disclosed the affected proprietary component, input path, or command-building operation that fails to neutralize special command elements. Exploitation requires an existing low-privilege local session and can compromise the confidentiality, integrity, and availability of the endpoint.
