A redirect from an HTTPS target to plain HTTP on the same host would send credential headers unencrypted. Compare the full origin, or at least the scheme, before keeping credential headers on a redirect. The IMDS hardening looks sound. One low-severity test-coverage item for bare IPv6 hosts remains open.

Review comments at @server/src/routes/proxy.ts:
- Around line 763-764: 在 isSafeRpcHost 接受裸 IPv6 地址后，更新 RPC URL 构造逻辑，将未加方括号的 IPv6
主机规范化为方括号形式，确保生成有效 URL；保存后下载和连接测试两条路径都应复用该规范化处理。
- Line 830: 更新 host 的保存校验，避免 host 为数字 0
等非字符串假值时绕过校验；仅允许空字符串作为特殊情况，其余值都必须先通过字符串类型校验，再执行 isSafeRpcHost 校验。
Review comments at @server/src/services/proxyService.ts:
- Line 191: 修正 `proxyService.ts` 中关于 `allowPrivate` 适用范围的注释，准确说明 WebDAV 的
`inlineUrl` 请求路径也会通过 `proxyRequest` 使用 `allowPrivate:
true`；不要保留“仅对已保存的配置放开”的错误声明。若实际安全边界确实要求仅允许已保存配置访问私有地址，则同步调整 WebDAV
路由的调用路径以满足该边界。

- Line 191: 更新 validateUrl 及其后的请求连接流程，确保校验并固定实际解析和连接的 IP 地址，拒绝连接到 IMDS
的地址；若通过出口策略实现，也须强制覆盖直接请求和代理请求，避免仅凭 URL 主机名校验后仍能访问 IMDS。
- Line 193: 更新 proxyRequest 中的 axiosConfig，禁用 Axios 自动重定向，或确保每次跳转前都对目标执行与初始 URL
相同的校验；AI 内联配置等非可信来源的重定向目标必须继续遵守严格限制，仅对获准来源保留 allowPrivate 例外。
