Summary

Harden input handling in apps/hot-update-cli/src/services/update-server.ts (flagged by multi_agent_ai).

Vulnerability

Field Value
ID V-002
Severity CRITICAL
Scanner multi_agent_ai
Rule V-002
File apps/hot-update-cli/src/services/update-server.ts:75
Assessment Defensive hardening

Description: The update server CLI tool relies on client-side credential storage with directory permissions (0o700/0o600) as the primary security control. Bearer tokens are transmitted without mandatory HTTPS enforcement, mutual TLS, or certificate pinning. An attacker obtaining the credentials file through malware, backup extraction, or social engineering can replay tokens to authenticate as a legitimate publisher.

Threat Model Context

This is a private Node.js application (not published to npm). Vulnerabilities affect this application's own runtime only.

Changes

  • apps/hot-update-cli/src/services/update-server.ts

Behavior Preservation

The change is scoped to 1 file on the vulnerable path.


This patch removes an exploit primitive — a code pattern that, while not independently exploitable today, could be chained with other weaknesses by automated exploit-development tooling. Proactive removal of such primitives raises the bar against increasingly capable automated attack tools.

Summary by CodeRabbit

  • 安全性改进
    • 更新服务器地址现已进行协议校验。
    • 仅允许 localhost127.0.0.1 使用 HTTP;其他服务器地址必须使用 HTTPS。
    • 使用不符合要求的地址时,系统将提示错误并拒绝连接。

Review Change Stack

Walkthrough

更新服务器凭据获取流程新增 URL 协议校验。本地地址可使用 HTTP,其他地址必须使用 HTTPS。

Changes

更新服务器协议校验

Layer / File(s) Summary
校验服务器 URL
apps/hot-update-cli/src/services/update-server.ts
getUpdateServerCredentials 允许 localhost127.0.0.1 使用 HTTP。其他非 HTTPS 地址会抛出错误。

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 5aa4d

The HTTPS safeguard blocks non-local HTTP endpoints, but some valid localhost development URLs using uppercase letters will fail instead of connecting. Normalize the parsed hostname before merging.

小兔检查服务器门,
HTTPS 链路稳又清。
本地 HTTP 留一扇,
远方地址须加密。
凭据安全过春风。

请使用解析后的 URL.hostname 判断本地地址。

serverUrlHTTP://LOCALHOST:3000http://LOCALHOST:3000 时,new URL(serverUrl) 会将 protocolhostname 规范化为小写,但当前正则直接匹配原始字符串,因此 isLocalhostfalse,随后触发 HTTPS 校验错误。请复用同一个 URL 对象的 protocolhostname
