+# Proxy Protocol 传输分析报告
+
+**日期**: 2026-05-07  
+**测试环境**: 20.118.172.127 (Server 1) ↔ 108.181.90.137 (Server 2)
+
+---
+
+## 1. 代码流程分析
+
+### 完整数据链路
+
+```
+前端 (proxyProtocol: 0|1|2)
+  → 后端 handler mutations.go:1936
+  → 数据库存储 forward.proxy_protocol (model.go:50)
+  → 控制面 buildForwardServiceConfigs (control_plane.go:1791-1796)
+  → handler metadata: {"proxyProtocol": 2}
+  → Agent metadata 解析 (metadata.go:42)
+  → handler.go:256 WrapClientConn()
+  → conn.go:14 HeaderProxyFromAddrs(byte(ppv), src, dst)
+  → conn.go:15 header.WriteTo(c)
+  → 目标服务器收到 PROXY protocol header
+```
+
+### 关键代码
+
+**写入 PROXY header** (`go-gost/x/internal/net/proxyproto/conn.go`):
+```go
+func WrapClientConn(ppv int, src, dst net.Addr, c net.Conn) net.Conn {
+    if ppv <= 0 {
+        return c
+    }
+    header := proxyproto.HeaderProxyFromrs(byte(ppv), src, dst)
+    header.WriteTo(c)
+    return c
+}
+```
+
+**Handler 调用** (`go-gost/x/handler/forward/local/handler.go:256`):
+```go
+cc = proxyproto.WrapClientConn(h.md.proxyProtocol, conn.RemoteAddr(), conn.LocalAddr(), cc)
+```
+
+- `src` = `conn.RemoteAddr()` → 客户端真实 IP ✅
+- `dst` = `conn.LocalAddr()` → agent 监听地址 ✅
+- `ppv` = 1 或 2 → 版本号正确 ✅
+
+---
+
+## 2. 实际传输测试结果
+
+### 测试方法
+
+1. 在 Server 2 启动 Python TCP 监听器，解析 PROXY protocol header
+2. 在 Server 1 用当前代码编译 gost，配置 `proxyProtocol: 2` 转发到 Server 2
+3. 通过 `nc` 发送测试数据，验证 Server 2 是否收到正确的 PROXY header
+
+### 测试结果
+
+| 版本 | 状态 | 接收到的 Header |
+|------|------|----------------|
+| **PPv2** | ✅ 成功 | `PP2 family=1 alen=12 SRC=127.0.0.1:45410 DST=127.0.0.1:20001` |
+| **PPv1** | ✅ 成功 | `PROXY TCP4 127.0.0.1 127.0.0.1 43816 20001` |
+
+### 测试详情
+
+**PPv2 原始数据**:
+```
+Got 28 bytes
+PP2 family=1 alen=12
+SRC=127.0.0.1:45410 DST=127.0.0.1:20001
+```
+
+**PPv1 原始数据** (hex):
+```
+50524f58592054435034203132372e302e302e31203132372e302e302e312034333831362032303030310d0a
+```
+解码: `PROXY TCP4 127.0.0.1 127.0.0.1 43816 20001`
+
+---
+
+## 3. 单元测试结果
+
+```
+go-gost/x/handler/forward/local/  → TestLocalForwardHandlerSendsProxyProtocolToTarget ✅
+go-backend/internal/http/handler/ → TestBuildForwardServiceConfigsSendsProxyProtocolToForwardHandler ✅
+go-backend/internal/store/repo/   → TestGetForwardRecordIncludesProxyProtocol ✅
+```
+
+全部通过 (3/3)。
+
+---
+
+## 4. 发现的问题
+
+### 问题 1: `WriteTo` 错误未检查
+
+**位置**: `go-gost/x/internal/net/proxyproto/conn.go:15`
+
+```go
+header.WriteTo(c)  // 返回 (int64, error) 被忽略
+```
+
+**影响**: 如果写入失败（连接已断开、网络错误等），后续数据传输会在没有 PROXY header 的情况下继续，目标服务器可能解析出错。
+
+**建议**:
+```go
+if _, err := header.WriteTo(c); err != nil {
+    return c  // 或包装一个带错误的 conn
+}
+```
+
+**严重程度**: 低（实际场景中，写入失败后 `Transport` 也会很快失败）
+
+---
+
+### 问题 2: 部署版本过旧
+
+**服务器状态**:
+
+| 服务器 | 组件 | 版本 | 状态 |
+|--------|------|------|------|
+| 20.118.172.127 | flux_agent | UPX 压缩，无法读取版本 | ✅ 运行中 |
+| 20.118.172.127 | paneld | `/app/paneld` | ✅ 运行中 |
+| 20.118.172.127 | /usr/local/bin/gost | v3.0.0 (go1.23.4) | 旧版，不支持 handler metadata 中的 proxyProtocol |
+| 108.181.90.137 | flux_agent | 8.8MB | ✅ 运行中 |
+
+**影响**: 旧版 gost 二进制不识别 handler metadata 中的 `proxyProtocol` 字段，PROXY protocol 功能在生产环境不可用。
+
+**验证**: 用旧版 gost 测试时，目标服务器收到的原始数据为空，无 PROXY header。
+
+---
+
+### 问题 3: 数据库 Schema 缺失
+
+**位置**: 20.118.172.127 的 `/app/data/gost.db`
+
+**当前 forward 表 schema**:
+```sql
+CREATE TABLE `forward` (
+    `id` integer PRIMARY KEY AUTOINCREMENT,
+    `user_id` integer NOT NULL,
+    `user_name` varchar(100) NOT NULL,
+    `name` varchar(100) NOT NULL,
+    `tunnel_id` integer NOT NULL,
+    `remote_addr` text NOT NULL,
+    `strategy` varchar(100) NOT NULL DEFAULT "fifo",
+    `in_flow` integer NOT NULL DEFAULT 0,
+    `out_flow` integer NOT NULL DEFAULT 0,
+    `created_time` integer NOT NULL,
+    `updated_time` integer NOT NULL,
+    `status` integer NOT NULL,
+    `inx` integer NOT NULL DEFAULT 0,
+    `speed_id` integer
+);
+```
+
+**缺失字段**:
+- `proxy_protocol` — PROXY protocol 版本
+- `max_conn` — 最大连接数
+- `ip_max_conn` — 每 IP 最大连接数
+- `ip_speed_id` — 每 IP 限速 ID
+
+**影响**: 后端无法存储和读取 proxy_protocol 配置，前端设置不会生效。
+
+---
+
+## 5. 结论
+
+| 维度 | 状态 | 说明 |
+|------|------|------|
+| **代码实现** | ✅ 正确 | 完整的写入链路，版本/地址正确 |
+| **单元测试** | ✅ 通过 | 3/3 测试覆盖 handler、repo、控制面 |
+| **实际传输 (新编译版)** | ✅ 成功 | PPv1 和 PPv2 均正确传输 |
+| **实际传输 (部署版)** | ❌ 不工作 | 旧版不支持 handler metadata 中的 proxyProtocol |
+| **数据库 Schema** | ❌ 缺字段 | 需要迁移添加 proxy_protocol 等列 |
+
+**总结**: 代码实现正确，PROXY protocol 传输逻辑无误。但生产服务器运行的是旧版本，需要升级 backend 和 agent 才能启用此功能。

+# 面板本体一键升级设计
+
+**日期**: 2026-05-04
+**状态**: 待审核
+**作者**: AI Assistant
+
+## 概述
+
+在 FLVX 管理面板中增加“面板升级”能力，使管理员可以在网页上检查 GitHub Release 并触发面板本体升级。目标是升级整套面板，而不是只升级转发节点或只替换后端二进制。
+
+本设计采用 Docker Compose 整套升级方案：后端容器通过受限的 Docker socket 能力更新宿主机部署目录中的 `docker-compose.yml` 和 `.env`，然后启动独立的升级 helper 容器，由 helper 拉取新版 backend/frontend 镜像并重新启动 `backend` 与 `frontend` 服务。
+
+## sub2api 参考结论
+
+sub2api 的一键升级不是在宿主机执行 `docker compose pull/up`。它的运行形态是单体 Go 服务：前端构建产物 embed 到后端二进制，容器内只运行 `/app/sub2api`。升级接口下载 GitHub Release 中匹配当前系统和架构的 `sub2api_<version>_<os>_<arch>.tar.gz` 以及 `checksums.txt`，校验后把当前 `os.Executable()` 指向的 `/app/sub2api` 改名为 `/app/sub2api.backup`，再把新二进制原子替换到原路径。重启接口延迟调用 `os.Exit(0)`，依赖 Docker Compose 的 `restart: unless-stopped` 拉起同一个容器。
+
+这种方式在 sub2api 的 Docker 部署中可行，是因为它的前后端在同一个二进制里。FLVX 当前是 `flux-panel-backend` 与 `vite-frontend` 两个容器，替换 `/app/paneld` 只能升级后端，不能升级前端页面。因此 FLVX 的“面板本体升级”需要更新 Compose 版本和两个镜像，而不是照搬二进制替换。
+
+## 目标
+
+1. 管理员可在面板上查看当前版本、最新版本、升级通道和升级能力状态。
+2. 管理员可一键升级整套面板 backend/frontend。
+3. 升级复用现有 GitHub Release 和 `FLUX_VERSION` 版本机制。
+4. 升级复用现有 GitHub 加速配置 `github_proxy_enabled` / `github_proxy_url`。
+5. 升级过程不接受任意命令、任意 URL 或任意 compose 路径。
+6. 环境不满足时清晰提示不可用原因，不静默失败。
+
+## 非目标
+
+1. 不实现 sub2api 式后端二进制替换作为本次主路径。
+2. 不支持从非本仓库 Release 下载升级资产。
+3. 不支持普通用户触发升级。
+4. 不支持在前端执行 shell 命令。
+5. 不修改 `install.sh` 或 `panel_install.sh` 的本地安装菜单逻辑；发布流程仍可能覆盖这些脚本。
+6. 不引入前端测试框架。
+
+## 影响范围
+
+### 后端
+
+- `go-backend/internal/http/handler/handler.go`
+- `go-backend/internal/http/handler/upgrade.go`
+- 新增 `go-backend/internal/http/handler/system_upgrade.go`
+- 新增 `go-backend/internal/http/handler/system_upgrade_test.go`
+- `go-backend/Dockerfile`
+
+### 部署模板
+
+- `docker-compose-v4.yml`
+- `docker-compose-v6.yml`
+
+### 前端
+
+- `vite-frontend/src/api/index.ts`
+- `vite-frontend/src/api/types.ts`
+- `vite-frontend/src/pages/config.tsx`
+
+## 运行前提
+
+升级能力仅在 Docker Compose 部署中可用，并要求后端容器具备以下条件：
+
+1. 容器内存在 Docker CLI，且支持 `docker compose version`。
+2. `/var/run/docker.sock` 挂载到后端容器。
+3. 宿主部署目录挂载到容器内固定路径，例如 `/opt/flvx-panel`。
+4. 环境变量 `PANEL_DEPLOY_DIR=/opt/flvx-panel`。
+5. 环境变量 `PANEL_BACKEND_CONTAINER=flux-panel-backend`，为空时默认使用 `flux-panel-backend`；值必须匹配容器名安全字符集 `[A-Za-z0-9_.-]+`。
+6. 部署目录内存在 `.env` 和 `docker-compose.yml`。
+
+如果任一条件不满足，检查接口返回 `capable=false` 和明确的 `reason`，升级按钮禁用。
+
+## 后端设计
+
+### API
+
+新增系统升级接口，路径使用 `/api/v1/system/*`，继续受现有 middleware 管控，仅管理员可访问。
+
+| 方法 | 路径 | 用途 |
+|------|------|------|
+| `POST` | `/api/v1/system/version` | 返回当前版本、升级通道、能力状态和可选最新版本 |
+| `POST` | `/api/v1/system/check-updates` | 强制查询 GitHub Release，返回最新版本和候选列表 |
+| `POST` | `/api/v1/system/upgrade` | 执行升级 |
+
+请求体：
+
+```json
+{
+  "channel": "stable",
+  "version": ""
+}
+```
+
+`channel` 使用现有节点升级的通道语义：`stable` 匹配纯数字版本，`dev` 匹配 `alpha` / `beta` / `rc`。`version` 为空时自动选择该通道最新 Release。
+
+`/api/v1/system/version` 返回：
+
+```json
+{
+  "currentVersion": "2.1.9-beta14",
+  "channel": "stable",
+  "latestVersion": "2.1.9",
+  "hasUpdate": true,
+  "capable": true,
+  "reason": "",
+  "deployDir": "/opt/flvx-panel",
+  "composeFile": "/opt/flvx-panel/docker-compose.yml",
+  "backendContainer": "flux-panel-backend"
+}
+```
+
+`/api/v1/system/upgrade` 成功返回：
+
+```json
+{
+  "version": "2.1.9",
+  "message": "升级 helper 已启动，面板服务将短暂重启",
+  "commands": [
+    "docker run -d --rm --volumes-from flux-panel-backend ...",
+    "docker compose pull backend frontend",
+    "docker compose up -d backend frontend"
+  ]
+}
+```
+
+返回的 `commands` 只用于 UI 展示固定步骤，不包含用户输入或 shell 拼接结果。
+
+### 版本来源
+
+当前版本优先从容器环境变量读取：
+
+1. `FLUX_VERSION`
+2. `VITE_APP_VERSION` 不在后端容器中可靠存在，不作为后端版本来源。
+3. 为空时返回 `dev`。
+
+发布流程已经在 `panel_install.sh` 写入 `.env` 的 `FLUX_VERSION`，Compose 模板需要把该变量传给 backend 容器，保证后端可感知当前版本。
+
+### Release 查询
+
+复用现有 `fetchGitHubReleases`、`resolveLatestReleaseByChannel`、`normalizeReleaseChannel`、`releaseChannelFromTag`、`releaseChannelLabel` 和 GitHub 加速配置能力。新增函数只负责筛选系统升级所需资产：
+
+- `docker-compose-v4.yml`
+- `docker-compose-v6.yml`
+
+是否下载 v4/v6 compose 文件通过当前部署目录中的 `docker-compose.yml` 判断：如果网络定义包含 `enable_ipv6: true`，选择 `docker-compose-v6.yml`；否则选择 `docker-compose-v4.yml`。
+
+### 升级执行器
+
+新增 `systemUpgradeExecutor`，职责明确分为可测试的小函数：
+
+1. `checkSystemUpgradeCapability()` 检查 Docker CLI、Docker socket、部署目录、`.env`、`docker-compose.yml`。
+2. `selectComposeAsset(currentCompose []byte) string` 选择 v4/v6 compose 资产。
+3. `updateEnvVersion(path, version string) error` 原子更新 `.env` 中的 `FLUX_VERSION`。
+4. `downloadCompose(version, assetName, dest string) error` 下载新版 compose 模板到临时文件。
+5. `currentBackendImage(containerName string) (string, error)` 获取当前 backend 容器镜像 ID。
+6. `startSystemUpgradeHelper(version string) error` 启动独立 helper 容器执行固定升级流程。
+
+升级流程：
+
+1. 获取全局升级锁，拒绝并发升级。
+2. 校验目标版本存在且不是 draft。
+3. 检查升级能力。
+4. 备份 `.env` 为 `.env.upgrade.bak`，备份 `docker-compose.yml` 为 `docker-compose.yml.upgrade.bak`。
+5. 下载目标版本的 compose 文件到部署目录临时文件。
+6. 原子替换 `docker-compose.yml`。
+7. 原子更新 `.env` 的 `FLUX_VERSION`。
+8. 通过 Docker socket 查询当前 backend 容器的镜像 ID。
+9. 使用当前 backend 镜像启动一个不属于 Compose 项目的临时 helper 容器。
+10. helper 通过 `--volumes-from flux-panel-backend` 继承部署目录挂载，并显式挂载 `/var/run/docker.sock`。
+11. helper 在 `PANEL_DEPLOY_DIR` 下执行 `docker compose pull backend frontend`。
+12. helper 等待 5 秒，让 SQLite WAL 等文件刷盘。
+13. helper 执行 `docker compose up -d backend frontend`，由 Compose 重建前端和后端。
+14. 后端接口在 helper 成功启动后立即返回；浏览器随后会经历短暂断线。
+
+PostgreSQL 模式不主动 pull 或重建 `postgres` 服务，避免无关数据库变动。新版 compose 文件仍保留 postgres 配置供后续手动迁移或重建使用。
+
+### 命令安全
+
+后端不暴露通用命令执行能力。后端只直接执行 Docker CLI 的固定参数，用于获取当前镜像和启动 helper：
+
+```go
+exec.CommandContext(ctx, "docker", "inspect", "-f", "{{.Image}}", backendContainer)
+exec.CommandContext(ctx, "docker", "run", "-d", "--rm", "--name", helperName,
+  "--volumes-from", backendContainer,
+  "-v", "/var/run/docker.sock:/var/run/docker.sock",
+  "-e", "PANEL_DEPLOY_DIR=/opt/flvx-panel",
+  "--entrypoint", "/bin/sh", imageID,
+  "-c", helperScript)
+```
+
+`helperScript` 由后端固定生成，不拼接用户输入：
+
+```sh
+cd "$PANEL_DEPLOY_DIR" && docker compose pull backend frontend && sleep 5 && docker compose up -d backend frontend
+```
+
+工作目录固定为 `PANEL_DEPLOY_DIR`。`PANEL_DEPLOY_DIR` 必须是绝对路径，且必须包含 `.env` 和 `docker-compose.yml`。接口输入只允许影响 `channel` 和已验证的 Release `version`。
+
+### 超时和错误处理
+
+1. Release 查询超时沿用现有 GitHub API 客户端超时。
+2. 下载 compose 文件使用 60 秒超时。
+3. 启动 helper 使用 30 秒超时，helper 内部命令不受原 HTTP 请求生命周期影响。
+4. 任一步失败时返回错误信息，并尽量保留 `.upgrade.bak` 供人工恢复。
+5. 如果 `.env` 更新后后续步骤失败，不自动回滚镜像或容器，避免误判导致更大破坏；错误信息提示备份文件位置。
+
+## 部署模板设计
+
+`docker-compose-v4.yml` 和 `docker-compose-v6.yml` 的 backend 服务增加：
+
+```yaml
+environment:
+  FLUX_VERSION: ${FLUX_VERSION:-dev}
+  PANEL_DEPLOY_DIR: /opt/flvx-panel
+  PANEL_BACKEND_CONTAINER: flux-panel-backend
+volumes:
+  - sqlite_data:/app/data
+  - /var/run/docker.sock:/var/run/docker.sock
+  - ./:/opt/flvx-panel
+```
+
+`go-backend/Dockerfile` 的 runtime 镜像通过多阶段构建从官方 `docker:27-cli` 镜像复制 Docker CLI 和 compose 插件到 Debian runtime 镜像，避免依赖 Debian apt 源中的 Docker 包可用性：
+
+```dockerfile
+FROM docker:27-cli AS dockercli
+FROM debian:bookworm-slim
+COPY --from=dockercli /usr/local/bin/docker /usr/local/bin/docker
+COPY --from=dockercli /usr/local/libexec/docker/cli-plugins/docker-compose /usr/local/libexec/docker/cli-plugins/docker-compose
+```
+
+实现时保留现有 Go builder 和 `/app/paneld` 入口，仅增加 Docker CLI stage 和复制步骤。
+
+helper 容器使用当前 backend 容器的镜像 ID 启动，而不是额外依赖 `docker:cli` 镜像。这样不引入新的镜像仓库依赖，并保证 helper 内可用的 Docker CLI 与当前后端一致。
+
+## 前端设计
+
+在 `vite-frontend/src/pages/config.tsx` 的基本设置或数据库占用附近增加“面板升级”卡片，避免隐藏在节点页导致误解为“节点升级”。
+
+展示内容：
+
+1. 当前版本。
+2. 最新版本。
+3. 更新通道选择，复用现有 `stable` / `dev` 语义和 `UpdateReleaseChannel` 本地存储。
+4. 升级能力状态：可用、不可用原因、Docker socket 高权限提示。
+5. 操作按钮：检查更新、立即升级。
+
+交互：
+
+1. 页面加载时调用 `/system/version`。
+2. 点击“检查更新”调用 `/system/check-updates`。
+3. 点击“立即升级”前弹出确认框，明确提示服务会短暂中断，并提示 Docker socket 具备宿主高权限。
+4. 升级请求只等待 helper 启动，超时设置为 60 秒。
+5. 成功后 toast 显示“升级已触发，面板将在数十秒内重启”，并可提示用户稍后刷新。
+
+## 安全边界
+
+Docker socket 挂载等同于给后端容器宿主机级别控制能力。这是本设计的主要风险。缓解措施：
+
+1. 仅 `/api/v1/system/*` 管理员接口可触发。
+2. 不提供任意命令执行接口。
+3. 不允许用户传入下载 URL。
+4. 不允许用户传入 compose 路径。
+5. 只升级本仓库 GitHub Release，且跳过 draft。
+6. 前端明确展示 Docker socket 权限提示。
+
+## 测试策略
+
+### Go 单测
+
+新增 `system_upgrade_test.go` 覆盖：
+
+1. `selectComposeAsset` 对 v4/v6 compose 内容的判断。
+2. `.env` 中已有 `FLUX_VERSION` 时更新值。
+3. `.env` 中缺少 `FLUX_VERSION` 时追加值。
+4. 缺少部署目录、`.env`、`docker-compose.yml`、Docker socket 时返回不可用原因。
+5. helper 命令构造固定命令序列，不拼接用户输入。
+6. 并发升级锁会拒绝第二个升级请求。
+
+### 手动/集成验证
+
+1. `go-backend`: `go test ./...`
+2. `vite-frontend`: `pnpm run build`
+3. 本地容器验证：启动 Compose 后检查设置页升级卡片可显示能力状态。
+4. 在无 Docker socket 的开发环境验证按钮禁用并显示原因。
+
+## 回滚与恢复
+
+自动升级失败时不做自动容器回滚。后端会保留：
+
+1. `.env.upgrade.bak`
+2. `docker-compose.yml.upgrade.bak`
+
+人工恢复步骤由错误信息提示：进入部署目录，按需恢复备份文件，再执行 `docker compose up -d backend frontend`。
+
+## 决策记录
+
+本设计已确定采用 Docker socket 整套升级方案，不再保留二进制替换作为本次实现路径。Docker socket 的权限风险通过管理员限制、命令白名单和前端提示控制。

+# FLVX 安全问题修复设计
+
+**日期**: 2026-05-13
+**状态**: 待审核
+**作者**: AI Assistant
+
+## 概述
+
+针对 PR #502 提到的安全问题，对 FLVX 后端认证、配置访问控制、配置写入保护、备份导出和 JWT 失效模型做一次集中修复。目标是优先消除高风险漏洞，同时保留当前必须兼容的登录页品牌配置读取和验证码兼容行为。
+
+本设计采用“高危项一次收口，结构性问题只分析不重构”的策略：本轮修复 MD5 密码存储、未受控配置读取、敏感配置写入、备份配置泄露和 JWT 长期有效且改密后不失效的问题；不修改“无 Cloudflare secret 时允许当前 captcha 兼容行为”，也不重构 `autoMigrateAll()` 与 `migrateSchema()` 的双迁移入口。
+
+## 背景
+
+当前主线存在以下已确认问题：
+
+1. `login`、`open_api/sub_store`、用户改密、管理员创建用户和管理员修改用户密码仍然使用 `security.MD5(...)`。
+2. `/api/v1/config/get` 在 middleware 的 `shouldSkip()` 中被匿名放行，导致任意调用方可以读取绝大多数配置。
+3. `updateConfigs()` 与 `updateSingleConfig()` 使用了两套不同的限制逻辑，敏感配置键在单项写接口中未被保护。
+4. `ExportAll()` 和 `ExportPartial(types=["configs"])` 会直接导出所有配置，包含 `jwt_secret`、`license_key`、`cloudflare_secret_key`。
+5. JWT 当前有效期为 90 天，且 token 在用户改密、禁用、角色变化后仍可继续使用到过期。
+
+同时存在两个重要约束：
+
+1. 登录页和未登录态品牌展示依赖匿名读取 `app_name`、`app_logo`、`app_favicon`、`app_bg_image` 和 `cloudflare_site_key`。
+2. `tests/contract/migration_contract_test.go` 已把“无 Cloudflare secret 时允许当前 captcha 兼容行为”定义为既有契约，本轮不改变。
+
+## 目标
+
+1. 新增和更新后的用户密码不再以 MD5 存储。
+2. 历史 MD5 用户可在首次成功认证时自动迁移到强哈希。
+3. 匿名请求不能再读取任意配置，只能读取明确的公开配置白名单。
+4. 通用配置写接口不能覆盖敏感配置键。
+5. 备份导出默认不泄露敏感配置明文。
+6. 用户改密、禁用或角色变化后，旧 JWT 应立即失效。
+7. 不破坏现有登录页品牌展示和 captcha 兼容行为。
+
+## 非目标
+
+1. 不重构 `open_api/sub_store` 的整体认证模型；该接口仍使用现有用户名和密码查询参数语义。
+2. 不实现完整 refresh token、session 管理后台或 token 黑名单体系。
+3. 不改变“无 Cloudflare secret 时允许当前 captcha 兼容行为”。
+4. 不在本轮重构 `autoMigrateAll()` 与 `migrateSchema()` 的启动流程。
+5. 不引入前端测试框架。

+## 设计决策
+
+### 已确认决策
+
+1. 本轮采用安全优先策略，允许收紧危险默认行为。
+2. MD5 密码采用“登录成功时自动迁移”的兼容方案。
+3. captcha 在未配置 Cloudflare secret 时的兼容行为保持不变。
+4. JWT 采用“最小可撤销”方案，而不是完整 session 体系。
+5. 双重迁移系统只分析，不在本轮中修改。
+
+### 迁移系统分析结论
+
+`autoMigrateAll()` 与 `migrateSchema()` 当前职责并不相同：
+
+1. `autoMigrateAll()` 负责表和列结构补齐。
+2. `migrateSchema()` 负责基于 `schema_version` 的数据修正，以及 PostgreSQL ID 默认值修复等兼容迁移。
+3. 现有 `repository_migrate_test.go` 已明确覆盖这两部分逻辑，说明它们在现有代码库中是被依赖的互补结构，而不是已确认的重复安全漏洞。
+
+因此本轮仅记录该分析结论，不把双迁移入口纳入改动范围，避免把安全修复扩展为启动流程重构。
+
+## 详细设计
+
+### 1. 密码存储与认证迁移
+
+在 `internal/security/` 中新增统一密码能力，替代各处直接使用 `security.MD5(...)` 的做法。
+
+建议新增以下接口：
+
+```go
+func HashPassword(plain string) (string, error)
+func VerifyPassword(storedHash, plain string) (ok bool, legacy bool)
+func IsLegacyPasswordHash(storedHash string) bool
+```
+
+哈希算法使用 `bcrypt`：
+
+1. `user.pwd` 当前为 `varchar(100)`，足以容纳 bcrypt 哈希。
+2. 不需要修改密码列长度，改动最小。
+3. 对当前 Go 后端来说，bcrypt 是最稳妥的强哈希升级路径。
+
+所有密码入口统一改为走这套能力：
+
+1. `login`
+2. `openAPISubStore`
+3. `updatePassword`
+4. `userCreate`
+5. `userUpdate` 中的管理员改密路径
+
+认证迁移规则：
+
+1. 如果数据库中存的是 bcrypt，则按 bcrypt 校验。
+2. 如果数据库中存的是历史 MD5，则先按旧逻辑校验。
+3. 历史 MD5 校验成功后，立即把 `pwd` 改写为 bcrypt。
+4. 自动迁移不仅在网页登录时执行，也在 `open_api/sub_store` 成功鉴权时执行，避免只使用订阅接口的老用户永远停留在 MD5。
+
+默认管理员种子账号仍保留当前默认密码语义和 `requirePasswordChange` 行为，但种子哈希改为 bcrypt，不再在新建数据库中写入 MD5 值。
+
+### 2. JWT 最小可撤销方案
+
+本轮不引入 refresh token 和黑名单表，而是做一个可以立即生效的最小撤销闭环。
+
+#### 数据模型
+
+在 `user` 表新增字段：
+
+- `password_changed_at BIGINT NOT NULL DEFAULT 0`
+
+该字段专门表示密码最后一次变更时间，不能复用现有 `updated_time`，原因是 `updated_time` 还会被流量、状态或其他用户资料更新触发，复用后会让非密码更新错误地使 token 失效。
+
+#### token 签发与校验
+
+继续使用现有 `iat` 声明，但把有效期从 90 天收紧到 7 天。
+
+token 校验分两步：
+
+1. 先做现有签名和过期时间校验。
+2. 再读取用户最小认证状态，确认：
+   - 用户仍存在
+   - 用户状态未被禁用
+   - 当前 `role_id` 与 token 中一致
+   - `claims.iat` 不早于 `password_changed_at`
+
+为避免 middleware 每次都查询完整用户对象，Repository 新增专用读取方法，只返回 token 校验需要的最小字段，例如：
+
+```go
+type UserAuthState struct {
+    ID                int64
+    RoleID            int
+    Status            int
+    PasswordChangedAt int64
+}
+
+func (r *Repository) GetUserAuthState(userID int64) (*UserAuthState, error)
+```
+
+#### 失效语义
+
+以下场景下，旧 token 应立即失效：
+
+1. 用户修改密码
+2. 管理员修改用户密码
+3. 用户被禁用
+4. 用户角色发生变化
+
+这会带来一次明确的兼容收紧：升级完成后，部分历史 token 可能因为寿命策略或认证状态变化而失效，这是安全优先下的可接受行为。
+
+### 3. 配置读取访问控制
+
+为了避免继续让 `/api/v1/config/get` 承担“有时匿名、有时鉴权”的混合语义，本设计将公开配置读取拆成单独的 public 端点。
+
+#### 端点设计
+
+保留现有受保护端点：
+
+- `POST /api/v1/config/get`
+
+新增公开端点：
+
+- `POST /api/v1/public/config/get`
+
+middleware 仅对白名单 public 端点放行，不再放行 `/api/v1/config/get`。
+
+#### 公开白名单
+
+匿名仅允许读取以下配置：
+
+1. `app_name`
+2. `app_logo`
+3. `app_favicon`
+4. `app_bg_image`
+5. `cloudflare_site_key`
+
+理由：
+
+1. 登录页与未登录态品牌渲染依赖前四项。
+2. 登录页在 captcha 开启时需要读取 `cloudflare_site_key`。
+3. 其他配置不应暴露给匿名方。
+
+前端调整规则：
+
+1. 登录页和 `site.ts` 中的未登录态品牌配置读取改走 `/public/config/get`。
+2. 登录后页面仍使用现有 `/config/get` 或 `/config/list`。
+3. 已登录页面中的配置读取逻辑不变，只是恢复为真正受 JWT 保护。
+
+### 4. 配置写保护统一
+
+当前 `updateConfigs()` 与 `updateSingleConfig()` 各自维护不同限制逻辑，是本次越权写入漏洞的根源。本轮把配置访问规则统一收口为一套辅助函数。
+
+建议新增配置策略定义：
+
+```go
+type ConfigAccessPolicy struct {
+    PublicReadable bool
+    Sensitive      bool
+    CommercialOnly bool
+}
+```
+
+由统一函数返回某个 key 的策略，再由：
+
+1. `public config get`
+2. `config get`
+3. `config list`
+4. `updateConfigs()`
+5. `updateSingleConfig()`
+
+共同复用。
+
+敏感配置键至少包含：
+
+1. `jwt_secret`
+2. `license_key`
+3. `cloudflare_secret_key`
+
+这些键的写入规则：
+
+1. 不允许通过通用配置写接口改写。
+2. 不允许通过公开读取接口读取。
+3. 非管理员在配置列表接口中也不能获得。
+
+商业版白名单键继续沿用现有语义，例如：
+
+1. `app_name`
+2. `app_logo`
+3. `app_favicon`
+4. `hide_footer_brand`
+
+但其判断逻辑同样统一走同一套策略函数，避免再次出现单接口漏判。
+
+### 5. 备份导出与导入脱敏
+
+备份系统改为“默认安全导出”，而不是“完整明文镜像”。
+
+#### 导出
+
+`ExportAll()` 和 `ExportPartial(types=["configs"])` 在写入 `backup.Configs` 前都先经过统一过滤函数，移除敏感配置键。
+
+敏感配置键与配置写保护列表保持一致：
+
+1. `jwt_secret`
+2. `license_key`
+3. `cloudflare_secret_key`
+
+#### 导入
+
+导入配置时，即使旧备份中带有上述敏感键，也会在导入前被丢弃，不允许通过备份恢复路径覆盖在线安全配置。
+
+该设计的取舍如下：
+
+1. 保留大部分业务配置、节点、转发、用户数据的恢复能力。
+2. 不再把备份文件当作核心密钥分发载体。
+3. `UserBackup.Pwd` 仍然保留，以维持用户恢复语义；在本轮密码升级后，这些值将是 bcrypt 哈希，而不是 MD5。
+
+### 6. captcha 兼容行为
+
+`captcha_enabled`、`cloudflare_site_key`、`cloudflare_secret_key` 的现有兼容行为保持不变。
+
+明确保持以下现状：
+
+1. 当未完整配置 Cloudflare key 时，当前 contract test 约定的兼容路径继续存在。
+2. 本轮不把 captcha 兼容逻辑从“兼容旧行为”切换为“严格校验”。
+
+这样可以避免把一轮安全修复扩展成登录流程行为变更，同时与用户已确认的范围保持一致。
+
+## 错误处理与兼容行为
+
+### 错误处理
+
+保持现有 API envelope：`{code, msg, data, ts}`。
+
+建议的接口行为：
+
+1. `POST /api/v1/public/config/get` 请求非公开 key 时返回 `403`。
+2. 受保护配置端点未登录时返回 `401`。
+3. 登录、订阅接口、改密接口继续返回通用认证失败，不暴露“用户名存在但密码错误”等细节。
+4. token 因签名错误、过期、改密、禁用或角色变化失效时，统一返回现有 `401` 语义。
+5. 备份导入中出现敏感配置键时，接口整体仍允许成功导入其他数据，敏感键静默忽略。
+
+### 保留兼容
+
+1. 登录页和未登录态品牌展示继续可用。
+2. 未配置 Cloudflare secret 时的 captcha 兼容逻辑继续保留。
+3. 历史 MD5 用户仍可继续认证，并在成功后自动迁移。
+
+### 刻意收紧
+
+1. 匿名方不再可读取任意配置。
+2. 通用配置写接口不再能写入敏感键。
+3. 备份不再导出敏感配置明文。
+4. 改密、禁用和角色变化会立即使旧 token 失效。
+
+## 测试设计
+
+本轮以 Go 单测和 contract test 为主，覆盖以下场景。
+
+### 密码迁移
+
+1. 历史 MD5 用户在网页登录成功后，数据库中的 `pwd` 被升级为 bcrypt。
+2. 历史 MD5 用户在 `open_api/sub_store` 成功鉴权后，同样触发迁移。
+3. 新建用户后落库的是 bcrypt，而不是 MD5。
+4. 管理员修改用户密码和用户自助改密后，落库的是 bcrypt。
+
+### JWT 最小可撤销
+
+1. 正常 token 仍可访问受保护接口。
+2. 改密后旧 token 失效。
+3. 用户被禁用后旧 token 失效。
+4. 用户角色变化后旧 token 失效。
+5. 过期 token 失效。
+
+### 配置访问控制
+
+1. 匿名访问公开配置成功。
+2. 匿名访问非公开配置失败。
+3. 已登录页面需要的普通配置读取仍然可用。
+4. `updateSingleConfig()` 无法修改敏感键。
+5. `updateConfigs()` 同样无法修改敏感键。
+
+### 备份脱敏
+
+1. `ExportAll()` 不包含敏感配置。
+2. `ExportPartial(types=["configs"])` 不包含敏感配置。
+3. 导入带敏感键的备份时，这些键不会被写回数据库。
+4. 非敏感配置和其他业务数据仍可正常导入导出。
+
+### 迁移系统回归
+
+1. 现有 `repository_migrate_test.go` 保持通过。
+2. 本轮不对 `autoMigrateAll()` 与 `migrateSchema()` 的职责边界做行为性改动。
+
+## 验收标准
+
+1. 数据库中不再新增 MD5 密码。
+2. 历史 MD5 用户可在首次成功认证后自动升级到 bcrypt。
+3. 匿名调用方不能再读取非公开配置。
+4. `updateSingleConfig()` 和 `updateConfigs()` 都无法改写敏感配置键。
+5. 备份导出默认不包含 `jwt_secret`、`license_key`、`cloudflare_secret_key`。
+6. 改密、禁用和角色变化后，旧 JWT 立即失效。
+7. 登录页品牌展示和 captcha 兼容行为不被破坏。
+8. 现有迁移测试和本轮新增安全测试全部通过。
+
+## PR #502 处置
+
+PR #502 的价值在于指出了真实问题，但其实现方式只是把讽刺性注释写进生产代码，并未修复漏洞。因此该 PR 不应合并。
+
+执行阶段的处置方式：
+
+1. 关闭 PR #502。
+2. 在关闭说明中指出：问题成立，但修复将通过正式代码与测试提交完成，而不是通过向源文件加入讽刺性注释。
+3. 后续在新提交中按本设计逐项修复。
