Additional hardening for queue access controls - #1152
cassidyjames wants to merge 12 commits into
Conversation
Any authenticated user, regardless of role or queue membership, could enumerate every MRT queue in an org and read or dequeue/lock every job in them -- including CSAM/NCMEC-designated queues -- because Org.mrtQueues, Query.manualReviewQueue, Query.getTotalPendingJobsCount, and Mutation.dequeueManualReviewJob all resolved queues via the *Dangerously*BypassPermissioning helpers with no permission or membership check. Switch those four call sites to getReviewableQueuesForUser, the existing membership-aware lookup already used correctly elsewhere (e.g. RoutingRule.destinationQueue, user.ts's reviewableQueues resolver). Add the missing auth check on ManualReviewQueue.jobs (defense-in-depth; not independently reachable today). The *Dangerously*BypassPermissioning primitives themselves are kept -- RoutingRule.destinationQueue uses the same bypass correctly, gated behind EDIT_MRT_QUEUES. Fixes #1150 Co-Authored-By: Claude <noreply@anthropic.com>
ManualReviewQueue.jobs checked that someone was logged in but never that the
caller could review the queue it was handed, and pendingJobCount and
oldestJobCreatedAt had no check at all. Queue objects reach these resolvers
from parents that don't establish membership themselves, so two traversals
still leaked jobs and queue metadata after the previous commit:
- User.favoriteMRTQueues keeps a favorite after access is revoked, and
Org.users is readable by any authenticated org member, so
`org { users { favoriteMRTQueues { jobs } } }` needed no permissions at all.
- RoutingRule.destinationQueue bypasses queue permissions for EDIT_MRT_QUEUES
holders, while getReviewableQueuesForUser returns nothing without VIEW_MRT,
so that permission combination could reach a queue it had no queues for.
Add assertQueueIsReviewable and apply it to all three fields. It mirrors
getReviewableQueuesForUser exactly, requiring VIEW_MRT and letting
EDIT_MRT_QUEUES see the whole org, plus a cross-org guard.
The reviewable-queue lookup is memoized on the GraphQL context rather than
called per field. The MRT dashboard asks for pendingJobCount and
oldestJobCreatedAt on every reviewable queue at once, so calling the lookup
inline would turn one dashboard load into two full queue fetches per queue.
Apollo builds a fresh context per request and the cache is populated before
the first await, so concurrent resolvers share one in-flight query.

The resolver handed the service only an org id, so getExistingJobsForItem scanned every queue in the org and returned full pending job payloads for any item, regardless of the caller's access to those queues -- the same bypass class as #1150. It now resolves the caller's reviewable queues up front and passes their IDs down, and the service filters the job_creations lookup to that set.
explicitlyAssignedReviewers, hiddenActionIds, and clearReportsTriggerActionIds still gated on authentication alone, so a revoked member (whose queue stays in favoriteMRTQueues) or an EDIT_MRT_QUEUES holder reaching the queue through RoutingRule.destinationQueue could read queue membership and moderation config. Extend assertQueueIsReviewable to all three, matching jobs/pendingJobCount/ oldestJobCreatedAt, and have the helper return the caller so the resolvers stop re-fetching it.

Queue names are unique per org and the fixture hardcoded `test-queue`, so the new getExistingJobsForItem scoping test failed with ManualReviewQueueNameExistsError as soon as it created a second queue in an org the fixture had already set up.

Scoping getExistingJobsForItem to the caller's queues left an empty queue set reaching the query builder, and Kysely compiles that filter to `in ()`, which Postgres rejects outright. Any caller without VIEW_MRT -- or with it but no queue memberships -- got a 500 where the correct answer is an empty list.

The resolver called getReviewableQueuesForUser directly, so a query that also asked for queue-scoped fields paid for two full queue fetches. It only needs the IDs, so the memoized lookup fits.

i think there may be a cache invalidation bug here. but there's also a broader question about whether we can avoid the complexity of caching by making our API more standard graphQL-like!

our graphQL API is a bit weird here, which means it's a lot of extra work to do these permission checks!
a standard graphQL would look more like
query {
queue(id: $ID!) {
pendingJobCount
oldestJobCreatedAt
# and so on...
}
}
then you'd only need to do the permission check once, in the queue resolver.
anyway, just a thought, i realize it's out of scope for this PR.

this would be better resolved by refactoring the API (see my other comment).
IMO we could also exclude the memoization here, for simplicity, and then refactor the API in a follow-up.

hmm, how does cache invalidation work here? what if the server runs for a long time, and permissions change -- we'd need to invalidate this cache in that scenario, right?
i'd suggest removing the caching for now and refactoring the API instead. (you can assign that to me if you agree!)

@taobojlen thanks for the review! I think some of this got handled directly in #1151, and there's a bunch of conflicts here now, so I'm going to close this PR. Please feel free to open any additional improvements or refactors separately. :) |

Follow-up to #1150
ManualReviewQueue.jobs checked that someone was logged in, but not that the caller could actually review the queue it was handed; pendingJobCount and oldestJobCreatedAt had no check at all. Queue objects can reach these resolvers from parents that don't establish membership themselves, so we could still leak jobs and queue metadata.
User.favoriteMRTQueues keeps a favorite after access is revoked, and Org.users is readable by any authenticated org member, so
org { users { favoriteMRTQueues { jobs } } }needed no permissions at all.RoutingRule.destinationQueue bypasses queue permissions for EDIT_MRT_QUEUES holders, while getReviewableQueuesForUser returns nothing without VIEW_MRT, so that permission combination could reach a queue it had no queues for.
Add assertQueueIsReviewable and apply it to all three fields.
The reviewable-queue lookup is memoized on the GraphQL context rather than called per field to avoid two full queue fetches per queue when loading the dashboard.
