From 75d1d56f93b9fc6d53ff96aa15eebc4fa66b86bc Mon Sep 17 00:00:00 2001 From: Shudipto Trafder Date: Mon, 26 Oct 2026 23:06:22 +0600 Subject: [PATCH 1/9] Enhance Checkpointer and Graph Services with Feedback Handling and Input Validation - Introduced FeedbackSchema for managing feedback on messages with size and depth limits. - Updated CheckpointerService to handle feedback updates and validate message context. - Enhanced GraphService to validate state types against the model's field types. - Refactored message validation to ensure only user messages and tool results are accepted. - Implemented checks for built-in state fields to prevent client overwrites. - Added tests for feedback handling, message validation, and state management. - Updated integration tests to reflect changes in message handling and permissions. --- CHANGELOG.md | 55 ++ CLAUDE.md | 21 +- tenxgraph_api/cli/config_editor/schema.py | 13 + .../src/app/core/auth/authorization.py | 12 +- .../src/app/core/auth/permissions.py | 11 +- .../src/app/core/auth/request_config.py | 92 ++- .../src/app/core/config/graph_config.py | 18 +- .../src/app/routers/ag_ui/service.py | 33 +- .../src/app/routers/checkpointer/router.py | 60 +- .../schemas/checkpointer_schemas.py | 41 +- .../services/checkpointer_service.py | 78 ++- .../routers/graph/schemas/graph_schemas.py | 22 +- .../routers/graph/services/graph_service.py | 38 +- .../integration_tests/test_isolation_idor.py | 4 +- .../test_client_config_isolation.py | 17 + tests/unit_tests/test_client_input_rules.py | 571 ++++++++++++++++++ tests/unit_tests/test_graph_service.py | 22 + tests/unit_tests/test_runs_config.py | 15 + tests/unit_tests/test_websocket_graph.py | 11 +- 19 files changed, 1086 insertions(+), 48 deletions(-) create mode 100644 tests/unit_tests/test_client_input_rules.py diff --git a/CHANGELOG.md b/CHANGELOG.md index b91fa621..9d9bbbfb 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -22,6 +22,61 @@ project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [Unreleased] +### Security + +- **Clients can no longer set `file_tool_root`, `workspace_root`, `tool_timeout` or + `node_timeout` in request `config`.** Core reads these keys from the run config, so a client + could point the prebuilt file tools at any directory on the server, or turn off the tool and + node time limits with `0` or `null`.

[PATCH 2/9] feat: add file deletion response schema and implement extraction limits - Introduced `FileDeleteResponse` schema for file deletion responses. - Enhanced `DocumentExtractor` to enforce size limits on text documents and manage concurrent extractions with bounded slots. - Added leading-byte checks for uploaded files in a new `signatures.py` module. - Implemented tests for extraction limits, ensuring oversized documents are skipped and concurrent extractions are managed correctly. - Updated media lifecycle tests to cover new features and edge cases related to file deletion and media URL checks. --- CHANGELOG.md | 42 + CLAUDE.md | 16 +- tenxgraph_api/cli/commands/skills.py | 30 + tenxgraph_api/cli/config_editor/schema.py | 25 + tenxgraph_api/cli/config_editor/validation.py |

Date: Tue, 27 Oct 2026 00:05:02 +0600 Subject: [PATCH 3/9] Implement per-thread run locking mechanism and enhance request validation - Added a new thread locking mechanism to ensure only one graph run occurs at a time on a thread, preventing interleaved execution. - Introduced a `thread_lock.py` module to manage thread locks using Redis or in-memory limits. - Implemented tests for thread locking behavior, including handling busy threads and cancellation of ongoing runs. - Enhanced request validation to enforce limits on the number of messages, content blocks, and character counts in requests. - Added unit tests to verify the correct behavior of request limits and error handling for oversized requests. - Updated integration tests to check for proper error responses when exceeding message limits. --- CHANGELOG.md | 50 ++ CLAUDE.md | 15 + .../src/app/core/auth/request_config.py | 64 +++ .../src/app/core/exceptions/handle_errors.py | 14 +- .../src/app/routers/ag_ui/converter.py | 25 +-

898cbe7569278525b236d9aecc85b94d5403fe95 Mon Sep 17 00:00:00 2001 From: Shudipto Trafder Date: Tue, 27 Oct 2026 10:50:03 +0600 Subject: [PATCH 4/9] Refactor JWT authentication tests and enhance error handling - Updated test for numeric user_id in JWT token to ensure it is stored as a string. - Added new tests for JWT claim validation, including user_id types and scope claims. - Enhanced JWT hardening tests with allowed host and origins settings. - Improved error sanitization tests to include allowed host and origins in production mode. - Added tests for timeout defaults in RunsConfig based on production and development modes. - Implemented strict production checks for environment variables in security configuration tests. - Enhanced WebSocket authentication tests to handle revoked tokens and session limits. --- CHANGELOG.md | 92 ++++++- CLAUDE.md | 19 +- SECURITY.md | 4 +- tenxgraph_api/cli/commands/api.py | 7 + tenxgraph_api/cli/config_editor/schema.py | 19 +-

Updated `store_service.py` to clarify client and server option keys, ensuring only allowed options are processed. - Enhanced `parse_output.py` to strip internal message details and handle error messages based on the environment (production vs development). - Modified tests to reflect changes in message output parsing and ensure internal fields are excluded from responses. - Added new tests to verify correct handling of missing messages, state validation errors, and logging behavior for client errors. - Implemented rate limiting tests to ensure proper eviction and sliding window behavior in memory-based rate limiting. --- CHANGELOG.md | 39 ++++ .../10xgraph/references/memory-and-store.md | 2 + .../10xgraph/references/state-and-messages.md | 2 +- .../src/app/core/auth/ownership_resolver.py | 6 +- .../src/app/core/auth/request_config.py | 2 + .../src/app/core/config/sentry_config.py | 14 ++ .../src/app/core/exceptions/handle_errors.py | 71 ++++-- .../app/core/middleware/rate_limit/memory.py | 88 +++++--- tenxgraph_api/src/app/routers/ag_ui/router.py | 7 +- .../src/app/routers/ag_ui/service.py | 21 +- .../src/app/routers/checkpointer/router.py | 8 +- .../services/checkpointer_service.py | 47 +++- tenxgraph_api/src/app/routers/graph/router.py | 44 ++-- .../routers/graph/services/graph_service.py | 24 +- .../routers/store/schemas/store_schemas.py | 20 +- .../routers/store/services/store_service.py | 10 +- tenxgraph_api/src/app/utils/parse_output.py | 44 +++- tests/cli/test_utils_parse_and_callable.py | 2 +- tests/integration_tests/test_ag_ui_api.py | 50 +++- tests/test_utils_parse_and_callable.py | 4 +- .../store/test_store_client_fields.py | 35 +++ tests/unit_tests/store/test_store_service.py | 26 +-- .../test_client_mistakes_not_500.py | 213 ++++++++++++++++++ .../unit_tests/test_error_context_details.py | 86 +++++++ tests/unit_tests/test_graph_router.py | 62 +++++ .../test_handle_errors_log_levels.py | 121 ++++++++++ tests/unit_tests/test_ownership_resolver.py | 21 +- tests/unit_tests/test_parse_output.py | 36 ++- .../unit_tests/test_rate_limit_memory_lru.py | 154 +++++++++++++ tests/unit_tests/test_sentry_config.py | 12 +- 30 files changed, 1142 insertions(+), 129 deletions(-) create mode 100644 tests/unit_tests/test_client_mistakes_not_500.py create mode 100644 tests/unit_tests/test_error_context_details.py create mode 100644 tests/unit_tests/test_handle_errors_log_levels.py create mode 100644 tests/unit_tests/test_rate_limit_memory_lru.py diff --git a/CHANGELOG.md b/CHANGELOG.md index 5ec1bd56..de09a0b5 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -24,6 +24,31 @@ project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ### Security +- **The memory rate limiter evicts in constant time at its key cap.** Keys are kept in + least-recently-used order, so a new key at the 50,000-key cap drops the oldest entry from the + front instead of sweeping and scanning every key (about 2.5 ms of blocked event loop per new + key before).
