code-audit
Authorized source-code security review and SAST workflows: Semgrep and CodeQL pattern hunting, dangerous API identification, and fix verification.

Source Code Security Audit
When to Use
- Reviewing a codebase for security defects with static analysis.
- Verifying that a vulnerability fix actually removes the flawed pattern.
适用场景
- 白盒审计、PR/差分安全审查
- Semgrep / CodeQL / Bandit / gosec 等 SAST
- 危险 API、注入点、鉴权缺失、加密误用
- 与
supply-chain-security/分工:本 skill 偏自有代码逻辑,供应链偏依赖与管道
工作流
1. 范围与威胁模型
□ 信任边界:用户输入、文件、反序列化、SSRF、鉴权中间件
□ 高价值资产:鉴权、支付、管理端、密钥处理
2. 自动扫描
semgrep --config auto .
# 或项目规则包
semgrep --config p/owasp-top-ten .
3. 人工验证(MUST)
□ 每个 SAST 命中:可达性?可利用性?误报?
□ 鉴权:IDOR/越权、缺校验、错误的多租户隔离
□ 注入:SQL/命令/模板/LDAP
□ 加密:硬编码密钥、ECB、自定义 crypto
4. 产出
Finding:位置 + 数据流 + PoC + 修复建议
可选 ATT&CK / CWE 编号
工具链
| 工具 | 语言/场景 |
|---|---|
| Semgrep | 多语言快速规则 |
| CodeQL | 深数据流(GitHub) |
| Bandit | Python |
| gosec / staticcheck | Go |
| SpotBugs / FindSecBugs | Java |
参考
references/sast-review-checklist.md../supply-chain-security/../api-security/../llm-security/(Agent 代码)
路由上下文
上游: MASTER R26 角色: ops/role-map.md cae 下游: 依赖漏洞 → supply-chain;运行时验证 → pentest-tools
任务完成自检
- [ ] 是否人工验证而非只贴扫描器输出?
- [ ] 是否含修复建议?
- [ ] 是否限定在授权仓库范围?
- [ ] Checklist?
Limitations
- Static analysis produces false positives; manual triage is required.
- Coverage depends on language support of the chosen SAST engine.
