CVE-2025-26476

Unauthorized access via hard-coded SSH private key

Published Aug 4, 2025 · Updated Feb 26, 2026

Hard-coded SSH keys in Dell ECS before 3.8.1.5 and ObjectScale 4.0.0.0 allow local users to gain unauthorized system access. The upgrade process preserves a hard-coded SSH cryptographic key, while clean deployments of the same releases do not contain the affected state; Dell has not published its file or authentication flow. Local access without prior authentication is required, and Dell does not specify the resulting account or permitted actions.
