- Line 93: Validate that bamboo_STAGING_API_KEY is non-empty before invoking
docker run in bin/deploy-bamboo.sh. Remove the local-staging-api-key fallback
from the deployed stack configuration in cdk/mmt/lib/mmt-stack.ts, ensuring
deployed CDK stacks use only the required staging API key environment value.
In `@cdk/mmt/lib/mmt-functions.ts`:
- Line 269: Create a dedicated IAM role for the four concept Lambda
integrations, restricting its S3 permissions to STAGING_CONCEPTS_BUCKET_NAME,
and replace s3LambdaRole with this role in those integrations. Leave the EDL
authorizer unchanged.
In `@serverless/src/createOrUpdateConcept/handler.js`:
- Line 87: Validate that body contains well-formed JSON before constructing or
sending PutObjectCommand in the createOrUpdateConcept handler, returning a 400
response for malformed non-empty input while preserving valid-body writes.
In `@serverless/src/deleteConcept/handler.js`:
- Around line 68-71: Update the delete flow around the HeadObjectCommand and
DeleteObjectCommand to remove the stale preflight existence check, making DELETE
idempotent so it does not rely on a race-prone read before deletion. If the
storage contract supports it, use a versioned or conditional delete instead,
ensuring a concurrent PutObject cannot cause a newer concept to be deleted.
In `@serverless/src/getConcept/handler.js`:
- Around line 88-91: Update both concept response handlers, getConcept and
getConcepts, to include a Cache-Control: no-store header alongside
defaultResponseHeaders. Apply the change at serverless/src/getConcept/handler.js
lines 88-91 and serverless/src/getConcepts/handler.js lines 90-93 so both
provider-scoped concept read responses disable browser caching.
- Line 32: Require a non-empty configured STAGING_API_KEY before comparing
credentials, so missing or empty deployment values and headers are rejected.
Apply the same guard to the authorization checks in
serverless/src/getConcept/handler.js (line 32),
serverless/src/getConcepts/handler.js (line 31), and
serverless/src/deleteConcept/handler.js (line 32); also remove the
local-staging-api-key fallback from cdk/mmt/lib/mmt-stack.ts.
In `@serverless/src/getConcepts/handler.js`:
- Line 64: Update the getConcepts handler’s s3ListObjects flow to paginate
ListObjectsV2 results until IsTruncated is false, passing each
NextContinuationToken into the subsequent request and aggregating all object
entries. Add a test covering a listing that spans two pages and verifies
concepts from both responses are returned.

Security Misconfiguration (CWE-732): Incorrect Permission Assignment for Critical Resource

Scope the concept Lambdas to the staging concepts bucket.
The four concept Lambdas use s3LambdaRole, which grants broad S3 actions on resources: ['*']. Create a dedicated role limited to STAGING_CONCEPTS_BUCKET_NAME and use it for these integrations. The EDL authorizer does not restrict the Lambda role's S3 permissions.

In `@serverless/src/stageConceptForProduction/handler.js`:
- Line 66: Update the configuration guard around productionApiHost and
productionStagingApiKey to also require productionMmtHost, preventing the
handler from proceeding when PRODUCTION_MMT_HOST is unset.
- Around line 78-82: Validate that productionUrl uses HTTPS before the
credentialed PUT request in the stageConceptForProduction handler, rejecting any
non-HTTPS or invalid URL before including productionStagingApiKey in the request
headers. Preserve the existing request flow for valid HTTPS URLs.
- Line 75: Update the URL construction near productionUrl to apply
encodeURIComponent to providerId, conceptType, and nativeId before
interpolation, preserving the existing path structure while preventing encoded
slashes and traversal segments from altering it. Add coverage for an encoded
slash and path traversal input.
- Line 78: Update the credentialed fetch call in the handler around
productionUrl to set redirect behavior to error, preventing cross-origin
redirects while sending Staging-Api-Key. Ensure PRODUCTION_API_HOST resolves
directly to the production API rather than relying on redirects.
In `@serverless/src/stagingApiKeyAuthorizer/handler.js`:
- Around line 20-21: Update the offline bypass condition in the authorizer

Something I fear that was lost in translation: Here Matthew and I decided that when a user stages a record they should receive a link that takes them straight to it in prod (something like /collections/staged/{unique-id}). The link is the connector between uat and prod. As it stands, this ticket still uses providerId as that connector. We want to move away from this rather than get into the weeds of what to do when a user stages a record under a provider that exists in UAT but not in prod. To fix this, the ticket will need to include a change to the createOrUpdateConcept so that it generates a unique id. The s3 key will have to change as well. It's currently {providerId}/{conceptId}/{nativeId}.json which prod won't be able to resolve from the uuid alone. Is it possible to key it just to the uuid? And finally, getConcept and deleteConcept should not call fetchProviders at all. There may be some other changes required here as well that I'm not thinking of. |
|
Overall looks good, you may also want to tests for native IDs containing /, #, and .., plus an S3 response with IsTruncated: true? The current tests pass but don’t cover these cases. |
I mostly agree with this, but I could be persuaded that including providerId is fine. Provider IDs between CMR environments don't alway match, so are you asking the user to provide a new providerId before they stage the collection? Would it be easier to present them with a dropdown of acceptable options once they move the staged concept into a draft? In that case you just need the unique ID in the URL.

Overview
What is the feature?
This PR adds a set of APIs for staging "concepts" (collections and other UMM concept types)
in MMT, backed by S3, plus a cross-environment "Stage for Production" forwarding flow
built on top of them. It adds Lambda handlers —
getStagedConcept,createStagedConcept,deleteStagedConcept, andstageConceptForProduction— plus a dedicatedstagingApiKeyAuthorizer. The S3-backed routes live under/staged/{conceptType}(PUT) and/staged/{conceptType}/{recordId}(GET, DELETE); the forwarding route isPOST /providers/{providerId}/{conceptType}/stage-for-production.createStagedConceptgenerates an opaquerecordId(UUID) and stores the concept under it;the get/delete routes address concepts by that
recordId. (It's namedcreateStagedConcept,not
createOrUpdateStagedConcept— everyPUTgenerates a brand-newrecordId, so it neveractually updates an existing record.)
What is the Solution?
Concept storage (S3)
s3.BucketStagingConceptsBucket(mmt-<stage>-staging-concepts): 30-dayobject-expiration lifecycle rule (
expire-staged-concepts),RemovalPolicy: RETAIN, publicaccess blocked, SSE-S3. Staged concepts are transient promotion artifacts.
{conceptType}/{recordId}.Handlers
createStagedConcept(PUT /staged/{conceptType}) — generates arecordId(UUID),writes the request body as-is to S3 at
{conceptType}/{recordId}viaPutObjectCommand,and returns
{ recordId }(the caller already knowsconceptType— it's in the requestpath). This is the only machine-to-machine route.
getStagedConcept(GET /staged/{conceptType}/{recordId}) — retrieves one concept viaGetObjectCommand, returned as{ concept, conceptType, recordId }.deleteStagedConcept(DELETE /staged/{conceptType}/{recordId}) — deletes viaDeleteObjectCommand, noHeadObjectpreflight: S3'sDeleteObjectis already asuccessful no-op on a missing key, so deleting a nonexistent concept returns success, not
a
404.stageConceptForProduction(
POST /providers/{providerId}/{conceptType}/stage-for-production) — forwarding Lambda,environment-agnostic (typical use is UAT → Production, but the target is whatever

fetchProviderscheck (providerIdcomes from the path and is used only forthis check — it is never forwarded), then
PUTs the body to${STAGING_TARGET_API_HOST}/staged/{conceptType}with aStaging-Api-Key: ${STAGING_TARGET_API_KEY}header. Reads the generatedrecordIdfromthe target's response and returns only
{ stagedConceptLink: ${STAGING_TARGET_MMT_HOST}/{conceptType}/staged/{recordId} };502if the target rejects or is unreachable,
500if the staging target is not fullyconfigured. The target's staging key never reaches the browser.
Authentication & authorization
stagingApiKeyAuthorizer— authenticates solely onthe
Staging-Api-Keyheader, compared againstprocess.env.STAGING_API_KEY. Fails closedwhen the env var is unset; bypasses on
IS_OFFLINE.cdk/mmt/lib/mmt-authorizers.tsrefactored to a sharedmakeRequestAuthorizerhelper;stagingApiKeyAuthorizeradded alongsideedlAuthorizer(EDL authorizer logical IDsunchanged).
STAGING_API_KEYis injected only into the authorizer's Lambda.createStagedConcept(PUT) →stagingApiKeyAuthorizeronly. The handler does no authof its own. It is unauthenticated when run via
bin/api.mjslocally (the local runnerinvokes no authorizers), the same as every other local route.
getStagedConcept/deleteStagedConcept→edlAuthorizeronly. EDL-authenticatedbrowser routes, but not provider-scoped — a staged concept is an opaque
recordIdwith no provider/native identity, so there is nothing to authorize per-provider. Any
authenticated MMT user may read/delete any staged concept.

StageConceptForProductionLambdauses the default Lambda role (no S3).cdk/mmt/lib/mmt-stack.ts— creates the bucket; addsStaging-Api-Keyto CORSallowHeaders; addsSTAGING_TARGET_API_HOST/_MMT_HOST/_API_KEY(dev-safedefaults; only meaningfully set where a forward target is configured). Synth guard: on
a deployed build (
NODE_ENV=production),cdk synththrows ifSTAGING_API_KEYismissing/placeholder, or if
STAGING_TARGET_API_HOSTis set whileSTAGING_TARGET_MMT_HOSTis missing or
STAGING_TARGET_API_KEYis missing/placeholder — the threeSTAGING_TARGET_*vars are optional only as a group (all unset, or all set together), notindividually.
bin/deploy-bamboo.sh— passesbamboo_STAGING_TARGET_API_HOST,bamboo_STAGING_TARGET_MMT_HOST,bamboo_STAGING_TARGET_API_KEY(alongsideSTAGING_API_KEYand the concepts bucket name) through Bamboo → Docker → CDK → Lambda. Thethree
STAGING_TARGET_*are defaulted to empty (${bamboo_STAGING_TARGET_*:-}), so theyare optional Bamboo plan variables — only forwarding environments need to define them.

Testing
