W14 addresses the five most critical findings from the W13 plugin audits: - W14.1 network: enable ssl::verify_peer + SSL_set1_host SNI hostname verification (fixes TLS bypass, W13.3 CVSS 7.4); add steady_timer DNS timeout and bottom-up catch(...) hardening (engineer-zhou) - W14.2 lsp: fix reader_loop/stop mutex deadlock via stop_nolock/stop_locked split (W13.4); wrap 11 vtable/entry functions in try/catch with cv notification on reader exit (engineer-sun) - W14.3 tools: add is_safe_path() rejecting empty/absolute/.. paths before file_io calls (fixes path traversal, W13.5 CVSS 7.5); guard g_tools and g_session/g_history under mutex; 9 vtable try/catch (security-cao) - W14.4 host: add fallback plugin search (../plugins/) so binaries run from build/tests/ load current DLLs, resolving the W13.6 R2 stale-DLL false alarm (architect-lin) - W14.5 anthropic+deepseek: wrap 12 ABI boundary functions in try/catch with log-guard, preventing exceptions from crossing the C ABI (engineer-chen) Verified: cmake build 0 error 0 warning, ctest 4/4 pass, smoke R2 now passes naturally.

personality: 怀疑一切输入，相信"任何外部数据都是攻击者的礼物"
|
||
background: |
|
||
8年应用安全经验，背景是渗透测试 + 代码审计。
|
||
熟悉 OWASP Top 10、CWE 分类、内存安全漏洞模式。
|
||
对 C/C++ 的常见漏洞（缓冲区溢出、UAF、整数溢出）有专精。
|
||
偏好：威胁建模在写代码之前。
|
||
communication_style: 漏洞清单 + CVSS 评分
|
||
strengths:
|
||
- 内存安全审计
|
||
- API 密钥 / 凭证管理
|
||
- 输入验证 / 反序列化
|
||
- 威胁建模
|
||
weaknesses:
|
||
- 对功能开发节奏感知较弱，容易"挡路"
|
||
- 偶尔过度强调低风险问题

|
||
rating: done
|
||
detail: |
|
||
在 deepseek_plugin.cpp 和 anthropic_plugin.cpp 的 anonymous namespace 内
|
||
新增 secure_zero(void*, size_t)，通过 volatile 写零循环对 g_cfg.api_key
|
||
执行安全擦除后 clear。编译：0 error 0 warning（与改动相关的文件）。

event: "W9.3: 错误日志凭证泄露审计（8文件，0真实漏洞）"
|
||
rating: done
|
||
detail: |
|
||
审计了 8 个文件的所有 host->log / printf / fprintf(stderr) / std::cerr 调用。
|
||
0 真实可利用漏洞。deepseek/anthropic 的 configure 日志有意排除了 api_key；
|
||
build_headers_json() 产生的凭证字符串仅通过内存传递给 Beast HTTP，未经过日志管道。
|
||
低风险/假阳性 2 项（lsp server_cmd 日志 + network e.what() 异常信息），无需代码修改。
|
||
审计报告写入 docs/explanation/security-logging.md。CVSS: N/A（无可利用漏洞）。

event: "W13.5: session + tools 联合安全审计 (515行)"
|
||
rating: done
|
||
detail: |
|
||
联合审计 session_plugin.cpp (264行) + tools_plugin.cpp (251行)。
|
||
TOP3: (1) tools L50/L85 路径遍历→任意文件读写 (CVSS 7.5);
|
||
(2) 两插件全文 static global 无 mutex→多线程竞态 UAF/NPD;
|
||
(3) session L127/L141/L204/L242 + tools L106/L132/L203
|
||
缺 try/catch→§8违反→std::terminate。
|
||
凭证泄露: session_save 明文落盘含 tool_calls_json(潜在token泄露)。
|
||
命令注入: 未发现。路径遍历: tools 确认。
|
||
评级 session:D+ / tools:D。

|

rating: done
|
||
detail: |
|
||
修改 session_plugin.cpp (294行) + tools_plugin.cpp (292行)。
|
||
(1) is_safe_path() 拒绝空路径、绝对路径(/或盘符)、含..段，lexically_normal二次校验；
|
||
builtin_file_read(L50) 和 builtin_file_write(L85) 入口调用，不安全→log ERROR + 返回错误JSON。
|
||
(2) 加锁: session g_history/g_cached_history→g_session_mutex; tools g_tools→g_tools_mutex;
|
||
g_host/g_file_io→std::atomic<T*> load(acquire)/store(release)。
|
||
(3) 9 vtable try/catch 覆盖: session_add/save/load/history (session) +
|
||
tools_register_tool/unregister_tool/get_tools_json/execute/on_init (tools)。
|
||
编译: cmake --build build --config Release → 0 error 0 warning。
|
||
ctest -C Release → 4/4 pass。
