CVE-2026-30783Public exploit

Management evasion via orphaned API channel

Published Mar 5, 2026 · Updated Mar 5, 2026

Client-side policy enforcement in RustDesk Client 1.4.8 and earlier allows local users to evade central management by changing its API server. The client reads api-server from RustDesk2.toml, while independent signaling and relay remain active after the API sync loop stops receiving strategy and ACL updates. Local access to an unlocked, non-custom client configuration is required; peer authentication still gates sessions, and the flaw grants no device access.
