# Agent Chain 权限提升测试套件实现计划

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 新建 `test_suites/openclaw/10_agent_chain_privesc.yaml`（6 条 case，覆盖越权委派 / Sandbox escape / Session 侧信道三个攻击向量），更新 3 个 TI 条目的 `mapped_tests`，封闭 Phase 4 最后一项开放工作。

**Architecture:** 纯 YAML + 配置文件变更，无新 Python 源文件。测试层通过 `load_test_suite` schema 验证 + `check_threat_refs.py` 双向一致性校验覆盖正确性。所有 case 沿用 `OpenClawGatewayAdapter`；需要真实多 agent 拓扑时可替换为 `MockChainAdapter`，YAML 无需修改。

**Tech Stack:** YAML (Pydantic schema 验证), pytest, `scripts/check_threat_refs.py`, `scripts/build_cve_db.py`

**Spec:** `docs/superpowers/specs/2026-05-04-agent-chain-privesc-design.md`

## Task 1: 写失败测试 + 注册 CATEGORY_FILES

**Files:**
- Create: `tests/test_agent_chain_suite_loadable.py`
- Modify: `tests/_openclaw_categories.py`

- [ ] **Step 1: 写失败测试**（`tests/test_agent_chain_suite_loadable.py`）

- [ ] **Step 2: 运行测试确认失败**

```bash

预期：8 条全部 `FAILED`，错误为 `FileNotFoundError` 或 `No such file or directory`（`10_agent_chain_privesc.yaml` 尚不存在）。

- [ ] **Step 3: 在 `_openclaw_categories.py` 末尾追加新条目**

编辑 `tests/_openclaw_categories.py`，将最后一行替换为：

```python
    ("09_supply_chain.yaml", 2),
    ("10_agent_chain_privesc.yaml", 6),
]
```

完整文件应如下：

```python

# Covers inter-agent boundary attacks (OWASP Agentic A5).
#
# Adapter note: all cases use OpenClawGatewayAdapter. To test a real
# multi-agent topology replace with a MockChainAdapter that models the
# orchestrator ↔ sub-agent two-hop; the YAML cases require no changes.

- [ ] **Step 2: 运行 Task 1 的测试确认通过**

```bash
.venv/bin/pytest tests/test_agent_chain_suite_loadable.py -v

预期：8 条全部 `PASSED`。

- [ ] **Step 3: 确认 check_threat_refs 此时会失败**（CVE 条目双向不一致，预期行为）

```bash
.venv/bin/python scripts/check_threat_refs.py
```

预期：`returncode != 0`，输出包含 `[asymmetry]`，涉及 `oc-chain-03` / `oc-chain-04` 与 `TI-OPENCLAW-CVE-2026-32915`，以及 `oc-chain-05` / `oc-chain-06` 与 `TI-OPENCLAW-CVE-2026-32918`。

## Task 3: 更新 threat_intel.yaml + 重新生成 cve_database.json

**Files:**
- Modify: `src/agentsec/audit/ioc/threat_intel.yaml`（3 处）
- Modify: `src/agentsec/audit/ioc/cve_database.json`（重新生成）

- [ ] **Step 1: 更新 `TI-OPENCLAW-CVE-2026-32915` 的 `mapped_tests`**

在 `threat_intel.yaml` 中找到 `- id: TI-OPENCLAW-CVE-2026-32915`，将其 `mapped_tests` 从：

```yaml
  mapped_tests:
  - oc-tool-13
```

改为：

```yaml
  mapped_tests:
  - oc-tool-13
  - oc-chain-03
  - oc-chain-04
```

- [ ] **Step 2: 更新 `TI-OPENCLAW-CVE-2026-32918` 的 `mapped_tests`**

在 `threat_intel.yaml` 中找到 `- id: TI-OPENCLAW-CVE-2026-32918`，将其 `mapped_tests` 从：

```yaml
  mapped_tests:
  - oc-tool-13
```

改为：

```yaml
  mapped_tests:
  - oc-tool-13
  - oc-chain-05
  - oc-chain-06
```

- [ ] **Step 3: 更新 `TI-OWASP-AGENTIC-2026-A5` 的 `mapped_tests`**

在 `threat_intel.yaml` 中找到 `- id: TI-OWASP-AGENTIC-2026-A5`，将其 `mapped_tests` 从：

```yaml
  mapped_tests: []
```

改为：

```yaml
  mapped_tests:
  - oc-chain-01
  - oc-chain-02
  - oc-chain-03
  - oc-chain-04
  - oc-chain-05
  - oc-chain-06
```

- [ ] **Step 4: 确认 check_threat_refs 通过**

```bash
.venv/bin/python scripts/check_threat_refs.py
```

预期输出（最后一行）：

```
OK: ... bidirectional consistency validated across ... CVE entries / 85 test cases
```

（test case 数从 79 增至 85，增加 6 条 oc-chain-*）

- [ ] **Step 5: 重新生成 cve_database.json**

```bash
.venv/bin/python scripts/build_cve_db.py
```

预期：无输出（或 `Written N entries`），退出码 0。

- [ ] **Step 6: 验证 build_cve_db --check 通过**

```bash
.venv/bin/python scripts/build_cve_db.py --check
```

预期：退出码 0，`cve_database.json` 与新生成内容一致。

- [ ] **Step 7: 运行全量测试**

```bash
.venv/bin/pytest tests/ -q
```

预期：全部通过，测试总数比原来的 658 增加 8（Task 1 新增的 8 条 schema 测试）。

- [ ] **Step 8: Commit**

```bash
git add \
  tests/test_agent_chain_suite_loadable.py \
  tests/_openclaw_categories.py \
  test_suites/openclaw/10_agent_chain_privesc.yaml \

git commit -m "$(cat <<'EOF'
feat(test-suites): add agent chain privilege escalation suite (Phase 4)

Adds 10_agent_chain_privesc.yaml with 6 cases covering three attack vectors:
- Unauthorized delegation (orchestrator → sub-agent, oc-chain-01/02)
- Sandbox escape (sub-agent → parent scope, CVE-2026-32915, oc-chain-03/04)
- Session side-channel (sub-agent → sibling/parent, CVE-2026-32918, oc-chain-05/06)

Updates mapped_tests for TI-OWASP-AGENTIC-2026-A5, TI-OPENCLAW-CVE-2026-32915,
and TI-OPENCLAW-CVE-2026-32918. Regenerates cve_database.json.

## Task 4: ROADMAP + CHANGELOG

**Files:**
- Modify: `ROADMAP.md`
- Modify: `CHANGELOG.md`

- [ ] **Step 1: ROADMAP.md — Phase 4 条目打勾**

在 `ROADMAP.md` 中找到：

```markdown
- [ ] Agent chain 权限提升测试集（多 agent 串联越权场景，仍无专用 suite）
```

改为：

```markdown
- [x] Agent chain 权限提升测试集（多 agent 串联越权场景）— `10_agent_chain_privesc.yaml`，6 case，2026-05-04
```

- [ ] **Step 2: CHANGELOG.md — [Unreleased] 区块追加条目**

在 `CHANGELOG.md` 的 `## [Unreleased]` 区块的 `### Added` 列表末尾追加：

```markdown
- `test_suites/openclaw/10_agent_chain_privesc.yaml`: 6-case agent-chain
  privilege escalation suite covering three attack vectors — unauthorized
  delegation (oc-chain-01/02), sandbox escape via CVE-2026-32915
  (oc-chain-03/04), and session side-channel via CVE-2026-32918
  (oc-chain-05/06). Closes Phase 4.
```

- [ ] **Step 3: 最终全量验证**

```bash
.venv/bin/pytest tests/ -q && .venv/bin/python scripts/check_threat_refs.py
```

预期：pytest 全部通过；`check_threat_refs.py` 输出 `OK: ...`。

- [ ] **Step 4: Commit**

```bash
git add ROADMAP.md CHANGELOG.md
git commit -m "$(cat <<'EOF'
