Browser Act Skill 安全审计

作者说它能做什么（原文）

Browser automation CLI for AI agents. NEVER run browser-act commands directly via Bash — always invoke this skill first. Use browser-act when a user mentions it by name, includes or asks to run a browser-act CLI command (e.g., browser-act browser list), or to: fetch, view, or extract rendered content from URLs, access pages requiring JavaScript, handle verification prompts, maintain authenticated

会不会运行危险命令？检查是否下载程序后直接运行、让他人远程控制电脑，或藏起要运行的命令。发现 1 项风险
中风险

首次使用会从 PyPI 安装并执行第三方软件包

原文依据：4 处
发现了什么

安装步骤从外部包仓库取得 `browser-act-cli`，随后入口要求执行其中的程序。本材料没有包含该软件包代码，因而无法验证其安装脚本或运行行为。

为什么需要注意

安装或运行阶段的软件包代码会获得当前用户进程所具有的本地权限；若包或供应链受损，可能访问该权限范围内的文件、环境变量和网络资源。

安装指令会通过 uv 获取外部的 `browser-act-cli` 包，随后要求运行该包提供的 `browser-act` 程序。提交材料未包含该包的实现，所以无法从这些行核验其安装或运行时行为。元数据要求首次安装取得用户确认，能降低意外安装风险，但不会消除第三方代码风险。

中风险

验证码求解会把挑战图片发送到外部服务

原文依据：2 处
发现了什么

隐私声明明确把验证码图片列为本地处理的例外，但没有给出接收方、传输地址、保存期限或删除政策。即使不发送 cookie 或整页内容，挑战图片自身也可能含有站点、会话或个人上下文。

为什么需要注意

外部服务可能看到并保留图片中的标识或敏感画面，从而造成数据泄露或把用户活动关联到特定网站。

声明明确表示调用 `solve-captcha` 时会把验证码挑战图片作为例外发送出去。可见材料称不发送 cookie 或页面内容，但没有说明接收方、保留期限或删除规则；图片具体包含什么也无法由源码确认。用户可限制不调用该功能，或要求作者披露接收与留存政策。

中风险

本地浏览器资料和日志会持久保存敏感会话数据

原文依据：2 处
发现了什么

该工具声明在 CLI 数据目录写入浏览器资料及每次运行的日志，并在本地存放 cookie、登录会话、页面内容和凭据。材料只说日志会轮换，没有说明目录位置、文件权限、加密或最终删除周期。

为什么需要注意

共享设备上的其他进程或用户、备份程序或设备失窃可能暴露登录状态、页面内容或凭据；保留下来的会话还可能被重用来访问账户。

该 Skill 声明会在 CLI 数据目录读写独立浏览器资料和运行日志，并在本地存储 cookie、登录会话、页面内容、凭据及浏览器资料。这些数据若被同机其他主体访问或设备受损，会影响账户与隐私。材料只说明日志每次运行轮换，未说明路径、权限、加密或清理期限；“轮换”也不等于永久保存。

中风险

连接现有 Chrome 可把已登录账户和标签页暴露给自动化

原文依据：3 处
发现了什么

`chrome-direct` 模式通过 CDP 连接本地 Chrome。虽然说明要求明确确认，但一旦允许，自动化可能处于用户现有浏览器的权限和登录上下文中，而不再受独立资料隔离。

为什么需要注意

错误、恶意动态指令或范围不清的任务可能读取已登录页面，或在真实账户中执行点击、表单和其他操作。

这段证据能说明什么

源码只说明 `chrome-direct` 会通过 CDP 连接本地 Chrome，并要求明确确认；没有说明它会连接用户当前资料、可访问哪些标签页，或是否继承现有登录状态。因此所述账户和标签页暴露是可能的后果，但现有材料不足以确定。用户可在确认前要求作者说明连接范围，并使用独立浏览器资料。

这项判断针对展示的代码和适用条件，不表示风险已经实际发生。

中风险

验证辅助可能绕过网站的反自动化控制

原文依据：4 处
发现了什么

该 Skill 宣称可处理验证提示，并提供交互式挑战和验证码辅助。用户对工具操作的同意并不等于目标网站授权绕过其验证机制。

为什么需要注意

在未获网站允许的情况下使用，可能违反服务条款、触发账户锁定或封禁，也可能让自动化继续执行本应由人工审查阻止的敏感流程。

这段证据能说明什么

材料宣称可处理验证提示、辅助交互式挑战，并仅在调用 `solve-captcha` 时发送挑战图片，但没有描述求解方法、目标站点规则或是否用于绕过访问控制。“需用户授权”只是工具侧同意，不能证明网站授权；同样，这些概括性说明也不足以证明实际绕过。用户应仅在目标网站许可自动化时启用验证辅助。

这项判断针对展示的代码和适用条件，不表示风险已经实际发生。

实际工作流由已安装的 CLI 动态提供，未包含在待审源码中

原文依据：3 处
发现了什么

入口文件要求代理立即执行 `browser-act get-skills`，并将其完整输出作为实际工作流。该输出及生成机制不在本次材料中，因此用户安装前无法核对之后会交给代理的具体指令。

为什么需要注意

如果软件包、分发渠道或动态内容被篡改，新增指令可能借助已获准的全部 `browser-act` 命令操纵浏览器、账户或数据。版本参数只能说明所请求的版本，不能从可见证据证明内容完整性。

入口明确称自身只是发现用的占位文件，并要求代理立即执行已安装 CLI 来取得“实际工作流”，且不得截断输出。该动态内容未出现在本次完整源码中，因此用户在安装前无法审查后续指令；这支持供应链与指令变更风险，但不证明其中必然含恶意行为。
