CVE-2026-49407— OpenHuman: Unauthenticated dictation WebSocket allows arbitrary audio streaming and unbounded memory growth

Quick assessment

Affected
tinyhumansai openhuman
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenHuman 是一个开源的智能体（agent）集成框架，提供桌面应用程序和 Rust 库形式。在 0.57.44 版本之前，其本地 WebSocket 端点缺乏客户端身份验证和浏览器来源（origin）验证。未经验证的客户端（包括能够访问该端点的恶意网页）可提交音频数据并触发资源密集型的语音转文本处理。更早的受影响版本还存在音频数据在无界缓冲区中持续累积的问题，使得攻击者可通过持续流式传输耗尽进程内存。上述问题可能导致系统性能下降、资源耗尽或应用程序崩溃。该漏洞已在 0.57.44 版本中修复。

Vulnerability Title
OpenHuman: Unauthenticated dictation WebSocket allows arbitrary audio streaming and unbounded memory growth
Source: CVE Program / CVE List V5
Vulnerability Description
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.
