+## 本地实证状态

+- 实证状态: `triage-manual`
+- 实证方式: `synthetic`
+- Artifact 模式: `synthetic`
+- 最近运行: `-`
+- 浏览器证据: `missing`
+- Run Bundle: `-`

+## 事件层
+
+- Canonical ID: `astro--CVE-2026-33769`
+- 系统: `astro`
+- 严重度: `low`
+- 来源置信度: `official`
+- 官方主源: https://github.com/withastro/astro/security/advisories/GHSA-g735-7g2w-hh3f
+- 影响版本: `introduced=2.10.10, fixed<5.18.1`
+- 修复版本: `5.18.1`
+
+## 对象与版本映射
+
+- Advisory Scope: `package`
+- 影响对象: `astro`
+- Entity Refs: `astro, astro--project--astro`
+- 版本置信度: `high`
+- 版本缺口: `-`
+- 版本证据源: `https://github.com/withastro/astro/security/advisories/GHSA-g735-7g2w-hh3f, https://nvd.nist.gov/vuln/detail/CVE-2026-33769, https://github.com/withastro/astro`
+
+## 受控验证流程
+
+- Workflow ID: `astro--CVE-2026-33769--workflow`
+- 漏洞家族: `ssrf`
+- 入口面: `remote-fetch-or-webhook-endpoint`
+- 需要角色: `editor-or-admin`
+- 触发向量: 对 `ssrf` 家族入口投递最小化、可审计、可回滚的受控输入，比较修复前后差异。
+- 请求/页面入口: `/webhook/test, /remote-fetch, /import-url`
+- 输入形态: 提交受控回环或哨兵 URL，验证协议、主机、IP 与重定向限制。
+- 预期不安全行为: 服务端向受控目标发起非预期请求。

+
+## 证据点与补丁验证
+
+### 服务端证据点
+
+- 应用日志中的命中路径、鉴权决策和异常栈
+- 反向代理或边界层日志中的请求头、来源 IP 与路由决策
+
+### 浏览器证据点
+
+- 基线截图与攻击后截图的 DOM/视觉差异
+- console、network 与 response metadata 中的异常信号
+
+### 数据库/文件系统证据点
+
+- 数据库中新增/越权读取的测试数据
+- 文件系统中新增上传样本、缓存条目或越权读取痕迹
+
+### 检测信号
+
+- WAF / reverse proxy 异常日志、访问日志和告警
+- 应用审计日志中的权限错误、重定向异常、模板渲染或上传落盘事件
+
+### 补丁验证步骤
+
+- 确认目标版本从 `introduced=2.10.10, fixed<5.18.1` 升级或回移到 `5.18.1`。
+- 保留同一组受控输入，在修复前后分别执行并比对响应、日志与浏览器证据。
+- 确认修复后仅保留预期业务行为，不再触发越权、回显、异常渲染或错误请求。
+- 补充 `ssrf` 族自动化回归，避免同类路径在插件、主题或代理链中回归。
+
+### 实验安全备注
+
+- 只使用回环地址、哨兵目标、无害样本或可回滚测试数据。
+- 禁止造成持久破坏、越权下载真实数据或不可回滚 side effect。
+- 如需浏览器证据，保留 baseline / proof 两份快照以及 console / network 记录。
+
+## 实验层
+
+- 仅用于自有资产、测试环境或已明确授权目标。
+- 允许公网可达目标，但必须满足资产归属或明确授权前提。
+- 最小化验证方式: 最小化验证、只读探测、可审计回显、受控注入。
+- 若该案例涉及插件、模块或扩展，应同时检查供应链与升级策略。
+- 禁止场景: 无归属证明或无明确授权的公网目标；知名公共网站或与测试无关的第三方资产；会造成持久破坏、数据越权下载或不可回滚影响的动作

+
+## 证据点与补丁验证
+
+### 服务端证据点
+
+- 应用日志中的命中路径、鉴权决策和异常栈
+- 反向代理或边界层日志中的请求头、来源 IP 与路由决策
+
+### 浏览器证据点
+
+- 基线截图与攻击后截图的 DOM/视觉差异
+- console、network 与 response metadata 中的异常信号
+
+### 数据库/文件系统证据点
+
+- 数据库中新增/越权读取的测试数据
+- 文件系统中新增上传样本、缓存条目或越权读取痕迹
+
+### 检测信号
+
+- WAF / reverse proxy 异常日志、访问日志和告警
+- 应用审计日志中的权限错误、重定向异常、模板渲染或上传落盘事件
+
+### 补丁验证步骤
+
+- 确认目标版本从 `introduced=0, fixed<8.0.0-20260127165411-fe3052073dc6, introduced=0, fixed<5.3.2-0.20260127165411-fe3052073dc6, introduced=10.11.0-rc1, fixed<10.11.11` 升级或回移到 `8.0.0-20260127165411-fe3052073dc6`。
+- 保留同一组受控输入，在修复前后分别执行并比对响应、日志与浏览器证据。
+- 确认修复后仅保留预期业务行为，不再触发越权、回显、异常渲染或错误请求。
+- 补充 `unknown` 族自动化回归，避免同类路径在插件、主题或代理链中回归。
+
+### 实验安全备注
+
+- 只使用回环地址、哨兵目标、无害样本或可回滚测试数据。
+- 禁止造成持久破坏、越权下载真实数据或不可回滚 side effect。
+- 如需浏览器证据，保留 baseline / proof 两份快照以及 console / network 记录。
+
+## 实验层
+
+- 仅用于自有资产、测试环境或已明确授权目标。
+- 允许公网可达目标，但必须满足资产归属或明确授权前提。
+- 最小化验证方式: 最小化验证、只读探测、可审计回显、受控注入。
+- 若该案例涉及插件、模块或扩展，应同时检查供应链与升级策略。
+- 禁止场景: 无归属证明或无明确授权的公网目标；知名公共网站或与测试无关的第三方资产；会造成持久破坏、数据越权下载或不可回滚影响的动作
