Summary (AI generated)

  • Added migration 20260908142414_revoke_remaining_anon_oracle_rpc_execute.sql to finish the anon oracle RPC hardening started in 20260824144021.
  • Revoked anonymous EXECUTE on get_org_members_rbac, is_member_of_org, update_org_invite_role_rbac, and update_tmp_invite_role_rbac (console JWT / authenticated callers retain access).
  • Fixed check_org_members_2fa_enabled and check_org_members_password_policy so missing orgs raise NO_RIGHTS instead of the distinguishable Organization does not exist error.
  • Synced supabase/schemas/prod.sql and extended security-definer-execute-hardening + security-oracle-rpc-hardening tests.

Motivation (AI generated)

Migration 20260824144021 only revoked a small subset of anonymous oracle RPCs. Several SECURITY DEFINER helpers remained callable with the public anon key and leaked distinguishable org/member outcomes (Organization does not exist vs NO_RIGHTS, or member enumeration). This closes that gap without breaking the published CLI path that still relies on anon + capgkey (get_user_id(text), get_org_members, check_org_members_*, etc.).

Business Impact (AI generated)

  • Reduces unauthenticated PostgREST probing of org membership and invite-management RPCs.
  • Preserves published @capgo/cli compatibility (identity + capgkey-scoped helpers unchanged).
  • Console flows that use signed-in JWT continue to work via the authenticated role.

Intentional anon exceptions (AI generated)

RPC Why anon stays
get_user_id(text) Published CLI identity resolution (20260825105544 restore)
check_org_members_2fa_enabled, check_org_members_password_policy, get_org_members Published CLI org admin checks via capgkey; bodies now use uniform NO_RIGHTS denials
exist_app, exist_app_v2 Return false without a valid capgkey — non-disclosing, required for API-key callers on the anon role

Test Plan (AI generated)

  • Extended tests/security-definer-execute-hardening.test.ts with ANON_ORACLE_REVOKED_PROCS grant assertions
  • Extended tests/security-oracle-rpc-hardening.test.ts with PostgREST probes for revoked RPCs and uniform NO_RIGHTS on org-member helpers
  • Verified new oracle tests pass against Tinbase (7/8 file tests; auth-login test requires full Docker seed)
  • tests/published-cli-rpc-contract.unit.test.ts passes locally
  • CI: CRITICAL — Published CLI / do not break old CLI green
  • CI: backend integration shards for security hardening tests green

Summary by CodeRabbit

  • Security

    • Anonymous access is no longer permitted for organization and membership RPCs.
    • Authenticated and service-level callers retain access.
    • Anonymous requests receive consistent authorization errors, helping prevent organization existence from being disclosed.
    • Internal requests can distinguish missing organizations from missing permissions.
  • Tests

    • Added coverage for RPC execution permissions, caller access restrictions, and role-specific errors.
    • Improved API-key test resilience against transient gateway errors.
    • Standardized request handling across API and app-operation tests.

Complete the anon oracle hardening wave started in
20260824144021 by revoking anonymous EXECUTE on org/member
enumeration RPCs that only the signed-in console needs, and
by aligning check_org_members_* denial paths so missing orgs
raise NO_RIGHTS instead of a distinguishable existence error.

Keep get_user_id(text) and capgkey-scoped CLI helpers on anon;
exist_app/exist_app_v2 remain anon-safe (false without auth).

📝 Walkthrough

Walkthrough

The migration revokes anonymous execution for four oracle RPCs and updates two member-checking functions to hide organization existence from non-internal callers. Tests validate role-specific errors, RPC permissions, API-key retries, and shared request helpers.

Changes

Oracle RPC hardening

Layer / File(s) Summary
RPC error handling contracts
supabase/migrations/..., supabase/schemas/prod.sql
The member-checking functions return ORG_NOT_FOUND to internal roles and NO_RIGHTS to non-internal callers when the organization is missing or permission is denied.
RPC execute permissions
supabase/migrations/..., supabase/schemas/prod.sql, tests/security-definer-execute-hardening.test.ts
Anonymous EXECUTE is revoked from four oracle RPCs. Authenticated and service roles retain EXECUTE.
Oracle RPC behavior validation
tests/security-oracle-rpc-hardening.test.ts
Tests cover anonymous denial, authenticated access, organization-existence masking, and service-role errors.
API key request reliability
tests/apikeys.test.ts
API key creation requests use a serialized helper with transient gateway retries and duplicate-key cleanup.
Test request normalization
tests/app.test.ts, tests/cron_stat_org.test.ts
App requests use the shared test helper. One cron test receives a formatting-only change.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 61f00

API-key test setup can fail before tests run when the POST warmup hangs, and retries can exceed their configured budget. Bound both paths before merge to keep CI reliable.

Use fetchTestRequest for subkey /app calls and retryUnsafe on
idempotent cron_stat_org POSTs so backend shard 2 survives cold
edge-function 502 responses under parallel CI load.

Anon oracle on these two helpers looks closed. Internal callers now collapse "missing org" into an empty result; left a note on that.

… RPCs

Address cubic P2s on #3280: remove retryUnsafe from POST /apikey and
cron_stat_org helpers, and add authenticated-caller assertions for the
four anon-revoked member/org RPCs so re-grants stay guarded.

@coderabbitai review

Keep anon/authenticated missing-org as NO_RIGHTS. service_role gets ORG_NOT_FOUND so deleted org is distinguishable from empty member lists (blehstbl).

HEAD 708114ae1 — addressed both actionable threads on tests/apikeys.test.ts:

  1. Capped postApiKey retry delay by remaining 15s deadline.
  2. Added deadline-aware POST/GET warmup via warmEdgeEndpointWithDeadline (AbortSignal + bounded retry delays).
