fix(qqbot): security hardening — gateway validation, atomic state, sanitized logging - #6200
Conversation
- Add validateGatewayUrl(): enforce wss:// protocol, warn on unexpected hostnames - Integrate into fetchGatewayUrl() return path - Truncate error body in fetchAccessToken() to 80 chars - Add 6 tests covering protocol rejection, wss acceptance, and edge cases
State persistence hardening:
- Atomic saveQQState() via tmp+renameSync with disposed guard and unref()
- Atomic flushQQState() with {mode: 0o600} permissions
- Entry type validation in restoreQQState() for chatTypeMap and msgSeqMap
Error log sanitization:
- Wrap all user-controlled data in process.stderr.write() with sanitizeLogText()
- Covering: connect retry, sendMessage errors, state persistence failures,
token refresh, malformed gateway, WebSocket errors, reconnect, and
C2C/group handler error paths

Hey @Eric-GoodBoy-Tech, thanks for the PR — the security hardening work looks valuable.
However, the PR body doesn't follow our PR template. A few things are missing or renamed:
- "What this PR does" — your "Summary" section covers this, but the heading should match the template exactly
- "Why it's needed" — the motivation is implicit in "Changes" but should be its own section explaining the problem being solved
- "Reviewer Test Plan" — your "Test Plan" section is missing the structured subsections: "How to verify", "Evidence (Before & After)", and the "Tested on" OS table
- "Risk & Scope" — your "Scope" section is missing "Main risk or tradeoff", "Not validated / out of scope", and "Breaking changes / migration notes"
- "Linked Issues" — referenced as "Dependencies" instead
- Bilingual
<details>block — the template requires a Chinese translation in a collapsible section
Could you reformat the PR description to match the template? The substance is good — it's just a matter of structure so reviewers can assess it efficiently.

The security hardening changes look solid — gateway URL validation enforces wss:// correctly, atomic state persistence follows the established temp-file + rename pattern, and sanitizeLogText is applied consistently across error paths. All 90 tests pass.

Reviewed the QQ Bot security hardening. The core changes are sound — wss:// scheme enforcement, atomic temp-file + renameSync state writes, sanitizeLogText() wrapping on every user-controlled stderr sink, and restore-time entry validation — and all 90 package tests, typecheck, and build pass. No blocking issues.
A few non-blocking suggestions inline, mostly about keeping the two atomic-writers from drifting again and matching the docs/labels to the new behavior.

LGTM ✅ — Security hardening is solid: gateway URL validation correctly enforces wss:// + *.qq.com, atomic state persistence (tmp+rename) is well-implemented, sanitizeLogText covers every user-controlled stderr sink, and state restore validation is thorough. 95 tests pass. 30 prior review threads all resolved.
Minor observations for future consideration (low-confidence, not blocking):
- Add
unlinkSync: vi.fn()to thenode:fsmock in send.test.ts for completeness - Consider adding a stderr log in
fetchGatewayUrlerror path (symmetry withfetchAccessToken) - Log total count alongside drop count in restore validation (e.g., "Dropped 3/200")

Review: QQ Bot Security Hardening (PR #6200)
This is a solid security hardening pass. The gateway URL validation (wss:// enforcement + *.qq.com hostname pinning), atomic state persistence (tmp+rename), error log sanitization via sanitizeLogText(), and state restoration validation are all well-motivated and mostly well-executed.
A few findings from reviewing the diff:
🟡 Unsanitized log sites remain in READY and RESUME handlers
Two process.stderr.write calls still interpolate unsanitized values:
- READY handler (~line 853):
sessionsis built from WS message data (chatId:sessionId) and written directly to stderr withoutsanitizeLogText(). - RESUME/sendIdentify (~line 898):
this.sessionIdis written directly to stderr.
Both are attacker-influenced (set via the WS connection) and could contain control characters or newlines. Since the rest of the PR systematically sanitizes all other stderr writes, these look like oversights.
🔵 restoreQQState returns true even when all entries are filtered
If the state file exists but every entry in every map is corrupt, all three filters produce empty Maps and the method returns true. The caller then believes state was successfully restored and proceeds with RESUME — but with empty routing maps, every message defaults to C2C routing.
Consider tracking whether any entries survived and returning false when all were dropped, so the caller falls back to a clean IDENTIFY.

There was a problem hiding this comment.
Bug: The filter callback uses destructuring ([k, v]) => which throws a TypeError when the array contains a non-array entry (e.g. null, 42, true). Although Array.isArray(raw.chatTypeMap) confirms the container is an array, JSON.parse happily produces arrays with non-tuple entries — [null, 42, ["a","c2c"]] is valid JSON.
The same pattern repeats for replyMsgId (line ~497) and msgSeqMap (line ~515).
Suggested fix — add an Array.isArray(e) guard before destructuring:
rawCT.filter(
(e) => {
if (!Array.isArray(e) || e.length !== 2) return false;
const [k, v] = e;
return typeof k === 'string' && k.length <= 256 && (v === 'c2c' || v === 'group');
},
)This also affects the existing tests — the 'filters chatTypeMap' test only uses well-formed tuples, so this crash path isn't exercised.

Suggestion: disconnect() has no idempotency guard. If called twice (e.g. from both the error handler and the shutdown path), flushQQState() runs twice, maps get cleared twice, and this.ws.close(1000) is called on an already-nulled socket. The new beforeExitHook cleanup added here is safe (guarded by the null check), but the method as a whole would benefit from an early return:
disconnect(): void {
if (this.disposed) return;
this.disposed = true;
// ... rest
}saveQQState already has a disposed guard and flushQQState is intentionally unguarded (documented in the comment below) — adding the guard at the top of disconnect() would be consistent with the saveQQState pattern.

There was a problem hiding this comment.
Suggestion: unlinkSync is used in the error-cleanup paths of both saveQQState() and flushQQState() (the catch block calls unlinkSync(tmpPath)), but it's not included in this mock. If any test triggers the write-error path, the real unlinkSync would be called on the actual filesystem.
Consider adding:
unlinkSync: vi.fn(),Also worth adding to the import on line 66 if any test needs to assert on it.

5/5 |
1) The gateway validator holds against real SSRF / downgrade / credential attacks
I compiled the PR's api.ts with esbuild and drove the real validateGatewayUrl() in plain Node — no vitest, no mocks. It correctly rejects the Tencent-Cloud-APIGW exfil vector, the broad *.tencent.com suffix, arbitrary hosts, the cloud-metadata IP, the suffix-spoof qq.com.evil.net (a case the tests don't cover — .endsWith('.qq.com') defeats it), all non-wss:// schemes, and strips embedded user:pass@ credentials while accepting the legit prod/sandbox gateways.
2) The tests are not vacuous — every guard was reverse-mutated
For each security invariant I reverted just that fix in the source and re-ran its protecting test. All 8 turned RED, proving the tests fail if the hardening regresses (not merely passing by construction).
3) Atomic persistence verified against a real temp dir (not the fs mock)
Using a QWEN_HOME redirect and the real node:fs, I drove a real QQChannel:
- atomic write —
flushQQStatewrites…state.json.tmp,renameSyncto the final path, mode0600, no.tmpremnant left behind; - torn-write survival — I sabotaged the
.tmppath so the write throws mid-flush (EISDIR, same shape asENOSPC/EACCES); the previous good file stays byte-for-byte identical — the atomic pattern genuinely prevents corruption; - restore filtering — a hostile on-disk file (unknown chat types, 500-char reply ids, negative/fractional seqs) is filtered down to only clean entries; corrupt JSON returns
falsewithout throwing; save→restore round-trips cleanly.
Adversarial review — no defects found
.endsWith('.qq.com')(dot-anchored) correctly rejectsevil-qq.comandqq.com.evil.net— no suffix-confusion hole.- The
beforeExithook isoff-before-onon each connect and removed ondisconnect()— no listener leak /MaxListenerswarning across reconnects. saveQQState(debounced) andflushQQStateshare the same.tmppath, butflushQQStateclears the pending timer first — no intra-instance race.
Notes for merge (non-blocking)
- Stale counts in the PR description: it says "19 tests / 78 pass"; the branch now has 103 (the description predates later commits). Cosmetic only.
- CI/state:
reviewDecision = CHANGES_REQUESTED,Test (ubuntu-latest)still pending; macOS/Windows show skipping (named-job placeholders). The local results above are stronger evidence for the test outcome than the pending CI leg. Please confirm the outstanding review threads are resolved before merging.
Verdict: the three security properties this PR claims — gateway SSRF/downgrade rejection, crash-safe atomic state, and restore-time validation — all hold under real, un-mocked, adversarial exercise. Code is sound and, from a correctness standpoint, mergeable once the review threads and the ubuntu CI leg are green.

✅ 维护者验证 —— 在 PR head（86615ea）本地真实构建并驱动
我把此 PR 检出到独立 worktree 做了端到端验证。除了重跑作者的测试套件外，我特意驱动了真实、未打桩的代码——因为已提交的测试把 node:fs 和 ./api.js 都 mock 掉了，单靠它们无法证明发布出去的代码行为正确。以下全部为绿。
| # | 验证项 | 方法 | 结果 |
|---|---|---|---|
| 1 | 已提交测试套件 | 在 PR head 跑 vitest run |

| 5 | 真实文件系统上的原子状态 | 真实 saveQQState/flushQQState/restoreQQState |
5/5 |
（截图见英文版）
1）网关校验器扛得住真实的 SSRF / 降级 / 凭证攻击
我用 esbuild 编译了 PR 的 api.ts，在纯 Node 里驱动真实的 validateGatewayUrl()——无 vitest、无 mock。它正确拒绝了腾讯云 APIGW 外泄向量、宽泛的 *.tencent.com 后缀、任意主机、云元数据 IP、以及后缀欺骗 qq.com.evil.net（测试未覆盖的用例——.endsWith('.qq.com') 能挡住它）、所有非 wss:// 协议；并在放行合法生产/沙箱网关的同时剥离了内嵌的 user:pass@ 凭证。
2）测试并非空过——每个防护点都做了反向变异
对每个安全不变量，我只把对应的那处修复回退，再跑保护它的测试。8 个全部翻红，证明这些测试在加固退化时会失败（而不是恒真地通过）。
3）原子持久化在真实临时目录上验证（非 fs mock）
通过 QWEN_HOME 重定向 + 真实 node:fs，驱动真实的 QQChannel：
- 原子写——
flushQQState先写…state.json.tmp，再renameSync到最终路径，权限0600，不留.tmp残留； - 中断写存活——我把
.tmp路径占成目录，让写入中途抛错（EISDIR，与ENOSPC/EACCES同形），此时之前的好文件逐字节不变——原子模式确实防止了损坏； - restore 过滤——磁盘上的恶意文件（未知会话类型、500 字符 reply id、负数/小数 seq）被过滤到只剩干净条目；损坏 JSON 返回
false而不抛错；save→restore 往返一致。
逆向审查——未发现缺陷
.endsWith('.qq.com')（带点锚定）正确拒绝evil-qq.com和qq.com.evil.net——无后缀混淆漏洞。beforeExit钩子在每次 connect 时先off再on，并在disconnect()时移除——重连过程中无监听器泄漏 /MaxListeners告警。saveQQState（防抖）与flushQQState共用同一.tmp路径，但flushQQState会先清掉挂起的定时器——实例内无竞态。
合并备注（不阻塞）
- PR 描述里的计数已过期： 描述写"19 个测试 / 78 通过"，当前分支实际是 103（描述早于后续提交）。仅为文案问题。
- CI/状态：
reviewDecision = CHANGES_REQUESTED，Test (ubuntu-latest)仍 pending；macOS/Windows 显示 skipping（named-job 占位）。就测试结果而言，上面的本地证据比 pending 的 CI 更有力。合并前请确认剩余 review 线程已解决。
结论： 此 PR 声称的三条安全属性——网关 SSRF/降级拒绝、崩溃安全的原子状态、restore 时校验——在真实、未打桩、对抗性的驱动下全部成立。代码从正确性角度是稳健的，待 review 线程与 ubuntu CI 转绿后即可合并。
验证环境：macOS · Node v22.22.2 · worktree 位于 86615ea。截图是实际捕获的终端输出的渲染。

[Suggestion] sessionId logged without sanitizeLogText — the RESUME logging site (~line 898) writes this.sessionId to stderr unsanitized. This value comes from the gateway server's READY dispatch (msg['d']['session_id']) — server-controlled data. Every other server/user-controlled value in the file is wrapped with sanitizeLogText(), but this one was missed. A compromised *.qq.com gateway could inject control characters via a crafted session_id. Fix: sanitizeLogText(this.sessionId, 128).
