Walkthrough

The backend adds a SecretManager abstraction with AWS and OpenBao implementations. The server creates one manager and injects it into route plugins. Secret retrieval, creation, and deletion no longer use route-local AWS clients.

Changes

Secret manager integration

Layer / File(s) Summary
Secret manager contract and backends
backend/src/services/secrets-manager/*, backend/src/types/arka-config-dto.ts
Adds the SecretManager contract, AWS and OpenBao implementations, path handling, and typed route options.
Secret manager selection and server wiring
backend/src/services/secrets-manager/index.ts, backend/src/plugins/config.ts, backend/src/server.ts
Selects OpenBao when configured, otherwise AWS. Shares the selected manager with route plugins and the price-update job.
Core route secret access
backend/src/routes/admin-routes.ts, backend/src/routes/deposit-route.ts, backend/src/routes/paymaster-routes.ts, backend/src/routes/metadata-routes.ts
Routes use injected secret-manager helpers for API-key retrieval, creation, and deletion.
Whitelist route secret access
backend/src/routes/whitelist-routes.ts
Whitelist handlers use the injected secret manager across all supported versions and contract operations.
Release metadata
backend/package.json, backend/CHANGELOG.md
Updates the backend version to 4.2.4 and records OpenBao support.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to be5e3

This migration can prevent existing deployments from starting, route secrets to an unintended backend, hang secret-dependent requests, mishandle provider errors, redirect secret paths, and leave secret and database state inconsistent; deletion behavior also does not preserve the existing recovery-window contract. These availability, security, and data-consistency risks should be fixed before merging.

Poem

I’m a rabbit with secrets tucked neat,
OpenBao or AWS makes the beat.
Routes share one manager bright,
Keys hop through the server just right.
No local clients burrow in sight.

🌐 Web query:

OpenBao KV v2 API POST create secret cas 0 check-and-set semantics

💡 Result:

In the OpenBao KV v2 secrets engine, the check-and-set (CAS) parameter is used to perform optimistic locking on write operations [1][2]. When using the POST create/update secret endpoint, setting the cas option to 0 specifically dictates that the write operation will only be successful if the secret key does not already exist [1][3]. If a key already exists, the write will fail if cas is set to 0, because the system interprets this as an instruction to only create the key if it has no prior version information [1][4]. For standard updates to existing keys, the cas parameter must match the current version number of the secret [1][2]. The cas parameter is typically passed within the options object of the request payload [1][5]: { "options": { "cas": 0 }, "data": { "key": "value" } } When cas_required is enabled (either globally on the engine or specifically for a secret), the cas parameter becomes mandatory for all write operations [1][6]. In such cases, if you are creating a new secret for the first time, you must set cas to 0 to satisfy the requirement while correctly indicating the lack of existing version history [1]. If you are writing to a key that has been soft-deleted, you must provide the version number that was current at the time of deletion, as cas set to 0 will not succeed on keys that still hold version data in storage [1][2].

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Fail fast for partial OpenBao configuration.

If only one OpenBao variable is set, this factory silently selects AwsSecretManager. A partially configured OpenBao deployment can then write new secrets to AWS, or fail later when AWS credentials are unavailable.

Validate that OPENBAO_ADDR and OPENBAO_TOKEN are either both set or both absent. Throw during startup when only one is set.

Proposed fix
 export function getSecretManager(): SecretManager {
-  if (process.env.OPENBAO_ADDR && process.env.OPENBAO_TOKEN) {
+  const hasOpenBaoAddr = Boolean(process.env.OPENBAO_ADDR);
+  const hasOpenBaoToken = Boolean(process.env.OPENBAO_TOKEN);
+
+  if (hasOpenBaoAddr !== hasOpenBaoToken) {

     return new OpenBaoSecretManager();
   }

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Normalize missing-secret failures across providers and preserve unrelated errors. AWS exposes a provider-specific not-found error, while an OpenBao 404 becomes a generic Error. The route handlers can therefore leak the backend error instead of returning INVALID_API_KEY, and the admin duplicate check can treat any failure as absence. Introduce a shared SecretNotFoundError, translate only provider-specific not-found responses to it, and update the affected consumers to catch only that error. Other secret-manager failures must propagate.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Bound OpenBao request behavior and make deletion semantics explicit. The HTTP calls have no deadline, so a stalled backend can leave route requests hanging; add a shared AbortController-based timeout and map timeout failures to a safe service error. Also, destroySecret ignores recoveryWindowInDays even though callers supply it, so either implement equivalent delayed deletion or reject the unsupported option explicitly.

Nice refactor overall - the SecretManager extraction is clean and the route changes look behavior-preserving. Left comments inline; the config validation one and the circular import are blockers, the rest are semantic differences between the AWS and OpenBao backends that I think we should iron out before this ships.

Also noticed OPENBAO_ADDR/OPENBAO_TOKEN aren't in .env.example or the README, and there are no tests for either implementation. Is that planned as a follow-up?

Type.String() || undefined doesn't do what it looks like - the || undefined part never kicks in, so this is just Type.String() and both of these end up as required properties. And since envVar passes process.env.OPENBAO_ADDR through with no fallback, any existing deployment that doesn't set these vars will fail at startup with .env file validation failed. Should be Type.Optional(Type.String()), or give them ?? '' defaults in envVar like the config block further down already does.

This import is a problem. "server.js" is a bare specifier that only resolves because of baseUrl in tsconfig (works under tsx/bun, breaks with plain tsc + node, and everything else in the repo uses relative paths), and it introduces a cycle: server.ts -> secrets-manager/index.ts -> openbao.ts -> server.ts. It only works right now because the constructor happens to run after server gets assigned.

Simpler to have getSecretManager() pass addr/token into the constructor and drop this import entirely. That also fixes the inconsistency where the factory reads process.env but this class reads server.config.

Deleting on the /data/ path is only a soft delete of the latest version in KV v2 - older versions of the secret (old private keys, mnemonics) stick around in OpenBao and can be undeleted, and _recoveryWindowInDays is silently ignored. That's quite different from AWS DeleteSecret, which schedules the whole secret for destruction. If you want parity, DELETE /v1/{mount}/metadata/{name} removes the secret and all its versions. Either way, worth documenting that the recovery window doesn't apply on the OpenBao backend.

A POST here will happily overwrite an existing secret (just bumps the version), whereas AWS CreateSecret fails on duplicates. The admin route does its own get-first duplicate check, but that leaves a race window that AWS used to close for us. You can get create-only semantics by sending options: { cas: 0 } alongside data - the write then fails if the secret already exists.

This now logs OPENBAO_TOKEN in plaintext - and that token has full access to every secret in the vault. I know it already logs HMAC_SECRET so the pattern isn't new, but let's not add another secret to it. Can we redact the token (ideally HMAC_SECRET too) before logging the config?

Small behavior change: the old code did JSON.parse(SecretString ?? '{}'), so an empty secret fell through to the clean INVALID_API_KEY responses in the routes. Now this throws and callers get a generic error from the catch path instead. Returning {} here would keep the existing API responses intact.

Reject traversal segments before constructing the OpenBao URL.

The API-key validation pattern accepts / and . because - defines a range. A crafted API key can therefore produce . or .. segments in prefixSecretId + body.apiKey. encodeURIComponent preserves those segments, and the URL parser normalizes .., allowing requests to leave the intended KV data path.

- Around line 46-47: Update the OpenBao configuration schema to make
OPENBAO_ADDR and OPENBAO_TOKEN optional, remove unset OPENBAO_* properties from
envVar before Ajv validation, and reject configurations where only one variable
is provided while preserving valid complete or absent pairs. Also update
server.log.info(config, "config:") to exclude the sensitive OPENBAO_TOKEN value.

- Line 108: Remove secretName from the console.log message in destroySecret,
since it may contain an API key; log only the mount or a non-reversible
identifier while preserving the destruction behavior.

Validate OpenBao configuration before startup and never log credentials.

Type.String() || undefined still creates required string schemas, so missing variables can fail validation before the AWS fallback runs. A partially configured OPENBAO_* pair can also silently select AWS, while configuration logging exposes OPENBAO_TOKEN. Make both settings optional, omit unset variables before validation, reject configurations where exactly one variable is set, and redact the token from logs.

Inject OpenBao addr/token into the secret manager to avoid the server import cycle.

Use CAS create-only writes to preserve duplicate-secret semantics, delete KV v2 metadata so all secret versions are removed, preserve AWS empty-secret fallback behavior, and redact sensitive config values before logging.

Fixes look good - verified the config validation no longer blocks AWS-only deployments, the circular import is gone, and the OpenBao delete/create semantics now match AWS. Thanks for the quick turnaround.
