Attack profile from CVSS 3.1 · CNA. Fix status from CNA. Impact type from CWE-306 and CWE-400.
Summary
OpenHuman versions before 0.57.44 expose a local /ws/dictation WebSocket endpoint without client authentication or browser-origin validation (CWE-306). An unauthenticated client, including a malicious web page that can reach the endpoint, can submit audio and trigger resource-intensive speech-to-text processing. Earlier affected versions also buffer audio without limit, so continuous streaming can exhaust memory and crash the application.

Description from the CNA
OpenHuman is an open-source agent harness available as a desktop application and Rust library. Before version 0.57.44, its local /ws/dictation WebSocket endpoint lacks client authentication and browser-origin validation. An unauthenticated client, including a malicious web page able to reach the endpoint, can submit audio and trigger resource-intensive speech-to-text processing. Earlier affected versions also accumulate audio in an unbounded buffer, allowing continuous streaming to exhaust process memory. These conditions can degrade performance, exhaust resources, or crash the application. This issue is fixed in version 0.57.44.
