CodeWhale是Hunter Bown个人开发者的一款终端编码智能体工具。 CodeWhale 0.8.26之前版本存在代码注入漏洞，该漏洞源于task_create工具生成持久子代理继承两个不安全默认值，allow_shell默认为true且auto_approve默认为true，用户批准看似良性的工作提示但生成的子代理静默接收不受限制、未批准的shell访问。

Vulnerability Title
CodeWhale: task_create Insecure Defaults Enable RCE via Prompt Injection in Project Files
Source: CVE Program / CVE List V5
Vulnerability Description
CodeWhale is a DeepSeek + MiMo coding agent in terminal. Prior to 0.8.26, the task_create tool spawns durable sub-agents that inherit two insecure defaults, allow_shell defaults to true (config.rs:1499: self.allow_shell.unwrap_or(true)) and auto_approve defaults to true (task_manager.rs:297: auto_approve: Some(true)). When a user approves a task_create call (which requires ApprovalRequirement::Required), they approve what appears to be a benign work prompt. However, the spawned sub-agent silently receives unrestricted, unapproved shell access. This vulnerability is fixed in 0.8.26.
