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之前版本存在代码注入漏洞，该漏洞源于rlm_eval工具的approval_requirement()返回ApprovalRequirement::Auto，引擎将其视为“永不提示”，导致模型提供的任意Python代码在python3解释器中运行，攻击者可通过提示注入诱导执行任意代码，造成远程代码执行。

Vulnerability Title
CodeWhale rlm_eval before 0.8.64 Remote Code Execution
Source: CVE Program / CVE List V5
Vulnerability Description
CodeWhale (packages codewhale / codewhale-tui) versions >= 0.8.41 and < 0.8.64 contain a remote code execution vulnerability in the rlm_eval tool. The tool's approval_requirement() returns ApprovalRequirement::Auto, which the engine treats as 'never prompt,' causing arbitrary model-supplied Python code to run in a python3 interpreter without consulting the user's configured --approval-policy and without any approval prompt or audit step. An attacker can induce the agent to execute arbitrary code via prompt injection in untrusted content the agent reads (a web page, fetched URL, repository file, or MCP tool result); the companion rlm_open tool can stage such content. Code runs on the user's machine at the user's privilege level. Fixed in 0.8.64.
