CVE-2025-26477Network attack vector

Authenticated remote code execution

Published Apr 17, 2025 · Updated Feb 26, 2026

Improper input validation in Dell ECS 3.8.1.4 and earlier allows remote authenticated users to execute code over the network. Dell identifies proprietary code as the affected component but has not disclosed the endpoint, input, or incorrect validation operation. Low-privileged ECS access is required; the published record does not establish the execution context or any ability to read data or interrupt service.
