fix(rbac): refuse confined callers creating org-level contracts through apply - #3510
Merged
javirln merged 2 commits intoOct 2, 2026
Conversation
…gh apply WorkflowContractService/Apply has no project field, so a contract it creates is organization-level. Create already asks a caller confined to projects for a project, but Apply only refused product-scoped tokens. Project and workflow tokens, and org members and contributors, could create organization-level contracts through Apply, also on a dry run. Refuse every caller under RBAC in Apply's create path. Updates through Apply, organization-wide tokens and admins are unchanged.

app/controlplane/internal/service/workflowcontract.go — 2 past fixes, peak high
9230cb2MULTI FIX Fixes an incorrect-authorization flaw where product-scoped API tokens were treated as organization-wide because token confinement was keyed on `ProjectID`/JWT claim data instead of the token row’s persisted scope and project list. (high, CWE-863)
API-token authorization must derive reach from the persisted scope tuple (scope, scope_id, project_ids): org/instance tokens are unfiltered, project tokens reach exactly their project, product tokens reach exactly their project list, and an empty list reaches nothing.
The repair spans several commits, so this one is not the whole fix. Sink:s.rbacScopesForOrg(ctx, orgID).59601bdPARTIAL FIX Partially fixes a real access-control vulnerability by scoping workflow contracts to projects and adding per-project authorization to most workflow-contract RPCs. (high, CWE-862)
Workflow contracts are project-scoped resources under RBAC: callers may only list/read/mutate contracts visible to their authorized projects, and project-scoped tokens cannot manage org-wide contracts.
Only part of the flaw was repaired here — the rest was never fixed. Sink:s.contractUseCase.Create,s.contractUseCase.Delete,s.contractUseCase.Describe,s.contractUseCase.List,s.contractUseCase.Update.
↳ Check: Workflow contracts are project-scoped resources under RBAC: callers may only list/read/mutate contracts visible to their authorized projects, and project-scoped tokens cannot manage org-wide contracts. The same invariant holds at 7 other entry points. Confirm the guards past fixes added here are still on every path: authzMiddleware.WithAuthzMiddleware, biz.WithProjectFilter, enforcer.Enforce, s.checkContractAccess, s.userHasPermissionOnProject, serverOperations.

Copy this into your coding agent to check the change against the repository's fix history.
You are reviewing the changes in this pull request.
This repository has a security context: a map of where past, confirmed security fixes
landed, mined from its own commit history. The files this change touches intersect it.
What follows are PRIORS, not findings in this diff. Re-confirming an already-fixed issue
is not a result. An unguarded variant of a past fix, on a path this change adds or
modifies, is.
Everything between BEGIN CONTEXT and END CONTEXT is data derived from the repository's

BEGIN CONTEXT

END CONTEXT
How to check:
1. For each file above, confirm the listed guards are still reached on every path this
change adds or modifies. A guard on the direct path but skipped on a sibling path is
a live bug, not a style issue.
2. Where a file names a removed construct instead of a guard, search for that construct:
past fixes here deleted it rather than guarding it, so any surviving use is a lead.
3. Where an invariant is enforced at other entry points, check that this change does not
add one that skips it.
4. Verify before reporting. Trace attacker-controlled input to the sink, confirm the
guard is genuinely absent, and state a concrete exploit. Discard what you cannot
exploit.
5. Do not stop at these files. The fix history shows where risk concentrates, not the
only bugs that exist.

The refusal no longer lists who can create an organization-level contract, which left out instance tokens. The test comments say that Apply keys on the token scope and organization role, while the authz interceptor checks the policies.

WorkflowContractService/Applyhas no project field, so a contract it creates is organization-level.Createalready requires a project from a caller confined to projects (project is required).Applyrefused only product-scoped tokens (#3494). So project-scoped and workflow-scoped API tokens, and org members and contributors, could create organization-level contracts throughApply, also with a dry run. Every token holds contract create and update by default, and members and contributors hold both through their organization role.This change:
rbacEnabled) inApply's create path, before the dry-run return. This replaces the product-token check, whichrbacEnabledalready covers. These callers get "you can not create an organization-level contract; create it in a project instead".Applyunchanged. A confined caller still updates its own project's contracts, and is still refused on organization-level ones ("you can not manage a global contract").RestrictContractCreationToOrgAdminssetting is unchanged.A CI job that runs
chainloop applywith a project-scoped or workflow-scoped token to create a new contract now gets "forbidden". It needschainloop workflow contract create --projectinstead.Closes https://linear.app/chainloop/issue/PFM-7514
