CVE-2026-18452Network attack vector

Unauthenticated device takeover via fixed API key

Published Jul 31, 2026 · Updated Jul 31, 2026

Hard-coded credentials in Rich Source DMS+ (Non-Mobile) 5.63 and earlier allow remote attackers to control all installed display devices. The management API authenticates requests with a fixed API key shared across installations rather than an installation-specific secret. No account or user interaction is required, and successful use grants control over every DMS+ device registered to the reachable management deployment.
