From 7f699d12020c5ffdb98775cf8a90911e11115f3b Mon Sep 17 00:00:00 2001 From: jony376 Date: Wed, 13 May 2026 04:53:08 -0700 Subject: [PATCH] Fix: enforce tenant authorization for `tenant_rerank_id` in retrieval flows (#14782) ### Related issues Closes #14781 ### What problem does this PR solve? Some retrieval endpoints accepted caller-supplied `tenant_rerank_id` and resolved it through `get_model_config_by_id(...)`. That helper loaded `TenantLLM` rows by global database id and returned decoded model configuration without checking whether the model belonged to the authenticated tenant or the dataset owner tenant. This meant dataset access was validated, but rerank-model selection was not. A caller who knew or could guess another tenant's `tenant_rerank_id` could attempt retrieval with a foreign rerank model config, creating a cross-tenant authorization gap for model usage. This PR closes that gap by making `tenant_rerank_id` resolution tenant-aware across the retrieval paths that accept it. ### Type of change - [x] Bug Fix (non-breaking change which fixes an issue) - [ ] New Feature (non-breaking change which adds functionality) - [ ] Documentation Update - [ ] Refactoring - [ ] Performance Improvement - [ ] Other (please describe): ### Solution - Extend `get_model_config_by_id(...)` to accept an optional `allowed_tenant_ids` set and reject `TenantLLM` rows whose `tenant_id` is outside that set. - Pass the allowed tenant scope from retrieval endpoints that accept `tenant_rerank_id`: - `api/apps/sdk/doc.py` - `api/apps/sdk/session.py` - `api/apps/services/dataset_api_service.py` - Use the authenticated tenant plus dataset-owner tenant ids already derived by each retrieval flow as the authorization boundary for rerank model selection. - Add focused unit coverage to assert unauthorized `tenant_rerank_id` values are rejected and that the allowed tenant set is propagated correctly. ### Testing - `python -m py_compile` on: - `api/db/joint_services/tenant_model_service.py` - `api/apps/services/dataset_api_service.py` - `api/apps/sdk/doc.py` - `api/apps/sdk/session.py` - Added unit tests in: - `test/testcases/test_http_api/test_file_management_within_dataset/test_doc_sdk_routes_unit.py` - `test/testcases/test_http_api/test_session_management/test_session_sdk_routes_unit.py` ### Notes for reviewers - This change is intentionally narrow: it affects only the `tenant_rerank_id` path, not the normal `rerank_id` name-based resolution path. - Local lint/syntax checks passed. - Full pytest execution could not be completed in this environment because the local test runtime is missing `strenum`, so the route-test files fail during collection before exercising the updated cases. --------- Co-authored-by: jony376 --- api/apps/sdk/doc.py | 7 ++++++- api/apps/sdk/session.py | 8 ++++++- api/apps/services/dataset_api_service.py | 14 +++++++++++-- api/db/joint_services/tenant_model_service.py | 21 ++++++++++++++++++- .../test_dify_retrieval_routes_unit.py | 16 ++++++++++++-- .../test_doc_sdk_routes_unit.py | 16 ++++++++++++-- .../test_session_sdk_routes_unit.py | 16 ++++++++++++-- 7 files changed, 87 insertions(+), 11 deletions(-) diff --git a/api/apps/sdk/doc.py b/api/apps/sdk/doc.py index cf297c4b25..a71b901617 100644 --- a/api/apps/sdk/doc.py +++ b/api/apps/sdk/doc.py @@ -492,7 +492,12 @@ async def retrieval_test(tenant_id): rerank_mdl = None if req.get("tenant_rerank_id"): -
