No caller-supplied body value or query parameter may override this. The JWT is the sole authoritative source of organization context. + +## JWT Claim Source + +`ITokenPayload` already carries `organization_id: string`. The Express middleware that verifies the JWT attaches the decoded payload to `req.user`. Controllers read `req.user.organization_id` and pass it down the stack. + +## Enforcement Points + +### Rule 1 — List Scoping (`GET /agents`) + +**Where:** `AgentController.listAgents()` → `AgentService.listAgents()` → `AgentRepository.findAll()` + +**Mechanism:** +1. `AgentController.listAgents()` sets `filters.organizationId = req.user.organization_id` unconditionally, overwriting any value that might have arrived in the query string. +2. `AgentRepository.findAll()` always includes `WHERE organization_id = $n` when `organizationId` is present in `IAgentListFilters`. Because the controller always sets it, this clause is always active. +3. The `owner` query parameter is applied as an additional `AND owner = $n` clause — it sub-filters within the org, never across orgs. + +**Result:** A caller from Org A cannot receive any agent record belonging to Org B, regardless of query parameters supplied. + +### Rule 2 — Ownership Guard (`GET`, `PATCH`, `DELETE` on `/agents/{agentId}`) + +**Where:** `AgentService.getAgentById()`, `AgentService.updateAgent()`, `AgentService.decommissionAgent()` + +**Mechanism:** +1. The repository fetches the agent record by `agentId` without org filtering (the ID lookup is always exact-match by primary key). +2. Immediately after retrieval, the service compares `agent.organizationId` against the `callerOrganizationId` parameter passed in from the controller. +3. If they do not match, the service throws `AuthorizationError` with code `AUTHORIZATION_ERROR` and message "You do not have permission to access this resource." +4. The controller's error handler maps `AuthorizationError` → HTTP 403. + +**Invariant:** An agent record is returned (or mutated/deleted) only if the caller's JWT org matches the stored org on that record. A non-matching ID returns 403, not 404 — this prevents org enumeration via timing differences. + +### Rule 3 — Register Scoping (`POST /agents`) + +**Where:** `AgentController.registerAgent()` + +**Mechanism:** +1. The controller ignores any `organizationId` field in `req.body`. +2. Before calling the service, it sets `organizationId = req.user.organization_id`. +3. The service and repository receive only the JWT-derived value. + +**Result:** It is impossible for a caller to register an agent under a foreign org, regardless of request body content. + +## Error Type + +A new (or existing) `AuthorizationError` class in the `SentryAgentError` hierarchy is used. It carries: +- `code: "AUTHORIZATION_ERROR"` +- HTTP status: `403` +- `message: "You do not have permission to access this resource."` + +This is distinct from the existing `ForbiddenError` (which covers role/permission checks) to allow fine-grained programmatic handling by API consumers. + +## Database Considerations + +No schema changes are required. The `agents` table already stores `organization_id`. The enforcement is purely at the application layer. Existing indexes on `organization_id` ensure the scoped list query remains performant. + +## Security Properties + +- **No information leakage:** Cross-tenant requests return 403, not 404. This means a caller from Org A cannot determine whether an agent with a given ID exists in Org B. +- **No parameter injection:** `organizationId` is never read from the request body or query string for scoping purposes — only from the verified JWT. +- **Defense in depth:** Enforcement is at the service layer, not just the controller, ensuring the invariant holds even if the service is called from other internal paths. diff --git a/openspec/changes/archive/2026-04-09-tenant-isolation-enforcement/proposal.md b/openspec/changes/archive/2026-04-09-tenant-isolation-enforcement/proposal.md new file mode 100644 index 0000000..c34a21e --- /dev/null +++ b/openspec/changes/archive/2026-04-09-tenant-isolation-enforcement/proposal.md @@ -0,0 +1,54 @@ +# Proposal: Enforce Tenant Isolation on All Agent Endpoints + +## Title +Enforce tenant (organization) isolation on all agent CRUD endpoints — P0 Security Fix + +## Problem Statement + +Field trial Test C.7 — Org Isolation Failure — has identified a critical security defect. +All five agent endpoints (`POST /agents`, `GET /agents`, `GET /agents/{agentId}`, +`PATCH /agents/{agentId}`, `DELETE /agents/{agentId}`) perform **no tenant isolation**. + +Any authenticated agent from Organization A can: +- Read the full agent list of Organization B (`GET /agents`) +- Read any individual agent record across any organization (`GET /agents/{agentId}`) +- Modify any agent's metadata across any organization (`PATCH /agents/{agentId}`) +- Decommission any agent across any organization (`DELETE /agents/{agentId}`) +- Register agents under any organization by supplying an arbitrary `organizationId` in the request body (`POST /agents`) + +The JWT issued by the system already contains an `organization_id` claim (present in `ITokenPayload`).
