Exploitation
Public or AI PoC available; prioritize validation
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Hunter Bown CodeWhale是Hunter Bown个人开发者的一个开源编程智能体。 Hunter Bown CodeWhale 0.8.41至0.8.64之前版本存在权限许可和访问控制问题漏洞，该漏洞源于exec_shell_interact（别名exec_interact）工具的审批要求自动返回，覆盖了代码执行工具的默认审批机制，可能导致攻击者通过注入不可信内容中的指令，在已批准的交互式shell中执行命令，造成权限提升。

Vulnerability Title
CodeWhale before 0.8.64 Privilege Escalation via exec_shell_interact
Source: CVE Program / CVE List V5
Vulnerability Description
CodeWhale versions >= 0.8.41 and < 0.8.64 contain a vulnerability in the exec_shell_interact (alias exec_interact) tool, whose approval_requirement returns ApprovalRequirement::Auto. This overrides the default Required approval for code-executing tools, so LLM-controlled stdin is written into an already-approved long-running interactive shell (e.g., a python3 -i REPL, mysql, ssh, or sudo -i session) without any approval prompt. An attacker who can inject instructions via untrusted content the agent ingests (a fetched page, MCP result, or repo file) can cause commands to run at the privilege level of that approved process. Fixed in 0.8.64.
