mongo options.autoEncryption.kmsProviders secret material (CSFLE: secretAccessKey / privateKey / clientSecret / local.key) is not on passthroughSecretPaths and is served cleartext on datasource reads

Found while implementing #13405 (nested credential positions off the passthrough table). That fix closes the class of nested positions that MIRROR a top-level credential spelling (password, authToken, and former aliases, judged at every object depth on both doors). It deliberately does NOT invent new secret NAMES: the client-measured residue stays passthroughSecretPaths in packages/spec/src/data/datasource-credential-redaction.ts, whose #9040 discipline is that every entry is measured against the client the driver spreads config.options into, never inferred from documentation.

The residue class has at least one more likely member family. The mongodb client's CSFLE surface reads secret material from the options passthrough at nested positions whose leaf names mirror no top-level credential spelling, so neither the name judgment nor the table covers them today:

options.autoEncryption.kmsProviders.aws.secretAccessKey (and sessionToken)
options.autoEncryption.kmsProviders.azure.clientSecret
options.autoEncryption.kmsProviders.gcp.privateKey
options.autoEncryption.kmsProviders.local.key

Mechanically true today (measured on the #13405 branch): redactDatasourceConfig('mongodb', ...) serves these positions back verbatim with no redactedKeys entry, because the leaf names are not credential-spelled and no table row names them.

What this card needs before any table edit: the #9040-style measurement against mongodb@7.5.0 (the pinned client) — does the client actually read these positions when spread from config.options (CSFLE requires the optional mongodb-client-encryption dependency, which may itself change the answer), and what does a redacted round-trip do to a working CSFLE config? Entries land on passthroughSecretPaths only with that measurement quoted, per the module docblock.

Not #13405's class (that card is the mirrored-spelling class, fixed by derivation); this is the client-measured-name residue the table exists for.

Triage: lands in packages/spec/src/data/datasource-credential-redaction.ts ⇒ domain:spec(唯一所有者), pm:queue, type Bug, priority:p1, security。

Bug + p1 依据:凭据脱敏面的声明目的是不把 secret 材料以明文送回 datasource 读取门,而 redactDatasourceConfig('mongodb', …) 今天对这四个位置原样回吐、且不留 redactedKeys 条目 —— 连「这里有东西被藏了」的痕迹都没有。涉及 AWS secretAccessKey / sessionToken、Azure clientSecret、GCP privateKey、local.key,全是可直接用于解密的材料。

以「带前提的裁决」入队 —— 前提是 #9040 纪律本身

① 裁决:确认为 secret 的位置补进 passthroughSecretPaths。

② 前提(⛔ 必须先测,这是模块 docblock 的硬纪律,不是分诊加的):

mongodb@7.5.0(本仓 pin 的客户端)确实会从 config.options 展开后读取这些位置。

#9040 纪律:每一条表项都必须对着「driver 把 config.options 展开进去的那个客户端」实测,⛔ 永不从文档推断。⇒ 派发令要求 dev 引用测量结果再落表项,与既有条目同格式。

⚠️ 卡还点出一个会改变答案的变量,必须一并测:CSFLE 需要可选依赖 mongodb-client-encryption —— 该依赖不在时,客户端是否仍读这些位置?两种情况的答案可能不同。

③ 同批必答:脱敏后的往返对一份可用的 CSFLE 配置做了什么? 卡明确要求这一问。若脱敏破坏了往返(例如把 local.key 换成占位符后配置无法再启动),那么单纯加表项会把一个泄露换成一次可用性事故 —— 这时正确形状是「脱敏 + 明确的写回语义」,回报,⛔ 不自行取舍。

范围边界(卡自设,分诊加固)

⛔ 不是 #13405 的类。#13405 修的是镜像顶层凭据拼写的嵌套位置(password、authToken 及旧别名,在两扇门上按任意对象深度判定),靠推导覆盖,且有意不发明新的 secret 名字。本卡是客户端实测名字的残余,归 passthroughSecretPaths 表 —— 这正是那张表存在的理由。⇒ ⛔ 不要把本卡做成对 #13405 推导规则的加宽,那会把「实测才入表」的纪律换成猜名字。

条款②

触 packages/spec/src/** ⇒ 路径肢命中,派发档位按 CONTRACT_REVIEW_TIER。内容肢由认领评论据实申报:加脱敏表项不改变接受/拒绝行为(不影响 datasource 能否被创建),大概率 Clause-②: no —— 但由派发席按实际 diff 判,⛔ 分诊不代判。

派发令要点(按分诊「带前提的裁决」):

② 前提先测:mongodb@7.5.0 实测四个位置确实从 config.options 展开后被读取,含/不含 mongodb-client-encryption 两种情况都测;⛔ 永不从文档推断(mongo config.options.auth.password is a fourth spelling of an inline credential — authorable, persisted cleartext, unredacted, and read by the client #9040 纪律)。测量结果引用进表项,与既有条目同格式。
③ 同批必答:脱敏后的往返对可用 CSFLE 配置做了什么;若脱敏破坏往返,回报 ⛔ 不自行取舍。
⛔ 不加宽 [security] datasource credential in a nested config position is served in cleartext on read — redaction is top-level-key-only #13405 的推导规则(不猜名字);residue 归 passthroughSecretPaths 表本身。

Added exactly the five measured positions to passthroughSecretPaths (mongodb) with the measurement quoted in the table docblock: aws.secretAccessKey, aws.sessionToken, azure.clientSecret, gcp.privateKey, local.key under options.autoEncryption.kmsProviders. No widening of the 13405 derivation, no invented name spellings; identity halves (accessKeyId, tenantId, clientId, email) and unmeasured neighbours (kmip.endpoint, keyVaultNamespace, schemaMap) stay served, pinned by a negative control. Round-trip answered: restoreRedactedConfig mirrors the redactor structurally, so an untouched Save keeps a working CSFLE config byte-identical (pinned end-to-end at the admin door); the served projection handed straight to the client fails loudly (TypeError: Failed to parse KMS provider aws: expected UTF-8 secretAccessKey; azure and gcp identical; local as empty object constructs with encryption still armed) — no silent-downgrade path, no write-back semantics change needed, no escalation.
