CVE-2026-49393

Full vulnerability record from the local CVENow database.

Description

OpenHuman is an open-source agent harness available as a desktop application and Rust library. Before 0.56.0, the core server protects HTTP POST requests to /rpc with bearer middleware but exposes Socket.IO rpc:request and chat:start handlers without equivalent transport or handler-level authentication. A local unauthenticated client can connect to the Socket.IO namespace and dispatch requests through the same protected controller path that rejects a missing bearer on /rpc. Depending on the selected method, the attacker can read configuration or health data, start agent flows, interact with integrated account APIs, alter local data, or stop and restart services. This issue is fixed in version 0.56.0.
