Use for authorized assessment of federated identity systems including SAML, OIDC, OAuth2 flows, SSO misconfiguration, and token confusion issues.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Identity Federation (SAML / OIDC / OAuth)

## ACTION REQUIRED（读完后立刻执行）

1. `NOW`: 读取 precedent-pentest；SSO 测试账号与 IdP/SP 范围入 scope
2. `NOW`: 禁止锁定真实用户账户的暴力尝试
3. `NEXT`: 抓包工具与文档（元数据 URL）
4. `ACT`: 协议流映射 → 常见错配 → 验证

## 适用场景

- SAML Response 签名/断言篡改面（经典缺陷模式）
- OIDC 隐式/授权码 + PKCE 缺失
- redirect_uri / state / nonce 问题
- IdP 与 SP 元数据、多租户 issuer 混淆
- 与 `api-security` JWT 攻击互补（本 skill 偏联邦与 SSO 流）

## 工作流

```text
□ 画清：User → SP → IdP → Token → SP
□ 收集：/.well-known/openid-configuration、SAML metadata
□ 检查：redirect_uri 精确匹配、state 绑定、PKCE
□ 检查：SAML 签名覆盖范围、algorithm 降级
□ 会话固定与登出失效
```

## 工具链

| 工具 | 用途 |
|------|------|
| Burp + SAML Raider 等 | 断言编辑（授权） |
| jwt_tool | JWT 段 |
| 浏览器 DevTools | 重定向链 |
| IdP 管理日志 | 审计 |

## 参考

- `references/sso-flow-checklist.md`
- `../api-security/` `../windows-ad/`（企业 IdP）

## 路由上下文

**上游**: MASTER R37  
**下游**: 纯 API JWT → api-security；云 IdP → cloud-k8s

## 任务完成自检

- [ ] 是否映射完整 SSO 流？
- [ ] 每个 Finding 是否有复现与影响？
- [ ] Checklist？

How to install

The exact contents, by fingerprint
mdr add novaestellar/novahaku/identity-federation@sha256:251f0d6939fd6d63

The line at the top of this page pins the label git:20260910.546fe86, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
