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 是一个开源的代理（agent）框架，提供桌面应用程序和 Rust 库形式。在 0.57.13 版本之前，若攻击者能够向已配置的外部通道发送消息，即可诱使该代理在未经人工审批的情况下创建持久化的 Shell 定时任务（cron jobs）。随后，调度器将以 OpenHuman 运行时用户的权限执行这些任务。此外，命令验证机制允许在命令前添加环境变量赋值，从而将原本允许的命令重定向至可执行的辅助程序。已展示的利用方式要求目标主机上已存在合适的辅助可执行文件。该漏洞可导致未经授权的持久化命令执行，进而

Vulnerability Title
OpenHuman allows remote inbound channel messages to create unapproved shell cron jobs leading to host command execution
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 0.57.13, an attacker who can send messages to a configured external channel can cause the agent to create persistent shell cron jobs without human approval. The scheduler later executes these jobs with the privileges of the OpenHuman runtime user. Command validation also permits leading environment assignments that can redirect allowed commands to executable helpers. The demonstrated exploit requires a suitable helper executable already present on the host. This can lead to unauthorized persistent command execution and compromise data and resources accessible to OpenHuman. This issue is fixed in version 0.57.13.
