Instead of returning a 400 error when return_to is passed without
control_plane_url configured, silently ignore it and proceed with
the normal same-origin SSO flow.
Two independent bugs prevented post-call OpenAI Moderation guardrail
results from reaching downstream logging callbacks (Langfuse, Datadog).
Bug 1: process_output_response() created a throwaway request_data dict,
so guardrail info written by @log_guardrail_information was discarded.
Fixed by threading the real request_data from the unified guardrail
dispatcher through all 13 BaseTranslation handlers, with litellm_metadata
injection preserved for third-party guardrails (Zscaler, Prompt Security).
Also extended to process_output_streaming_response for consistency.
Bug 2: The @log_guardrail_information decorator collapsed the full
moderation API response (categories, scores, flagged status) to "allow".
Fixed by overriding _process_response/_process_error on
OpenAIModerationGuardrail to stash and log the full response, following
the established Model Armor pattern.

* fix PEP 479 regression in __anext__ sync iterator exhaustion
asyncio.to_thread re-raises thread exceptions inside a coroutine, where
PEP 479 converts StopIteration to RuntimeError before any except clause
can catch it. Add _next_sync_or_exhausted() module-level helper that
catches StopIteration in the thread and returns a sentinel instead, then
raise StopAsyncIteration in the coroutine.
Also rewrites the non-blocking test to use asyncio.gather() instead of
asyncio.create_task() (which returned None on Python 3.9 / pytest-asyncio
in CI), and adds an exhaustion regression test that drains the wrapper
fully and asserts no RuntimeError leaks out.

* feat: add git-subdir source type to claude-code/plugins API (#24223)
Support a third plugin source type `git-subdir` alongside the existing
`github` and `url` types, as documented in the official Claude Code
plugin marketplaces spec.
New format: {"source": "git-subdir", "url": "...", "path": "subdir/path"}
- Validates url and path fields are present and non-empty
- Rejects absolute paths, '..' segments, backslashes, and percent-encoded
traversal sequences (including double-encoded variants via regex check)
- Extracts path validation into _validate_git_subdir_path() helper
- Updates Pydantic field description to document all three source types
- Adds isValidUrl() check for url/git-subdir source types in the UI form
- Adds "Git Subdir" option to the UI form with a required Path field
- Adds unit tests covering success, update, missing/empty fields,
path traversal variants, and unknown source type

Adds a control plane capability that enables a central admin instance
to manage multiple regional worker proxies from a single UI.
Backend:
- Worker registry loaded from YAML config (worker_id, name, url)
- /.well-known/litellm-ui-config exposes is_control_plane and workers list
- /v3/login + /v3/login/exchange: opaque code exchange for cross-origin
username/password auth (JWT never in URL/logs, single-use 60s TTL)
- SSO cookie handoff with return_to → opaque code → exchange
- _validate_return_to: full origin validation (scheme+hostname+port)
- Startup warning when control_plane_url set without Redis
- Both /v3 endpoints gated behind control_plane_url config
Frontend:
- Worker selector dropdown on login page (gated behind is_control_plane)
- Cross-origin SSO code exchange handling on callback
- switchToWorkerUrl: localStorage-persisted worker URL for API calls
- useWorker hook: shared worker state management
- WorkerDropdown in navbar for switching workers
- Logout/switch clears worker state from localStorage
Tests:
- 7 tests for /v3/login + /v3/login/exchange
- 10 tests for _validate_return_to
- 2 tests for control plane discovery endpoint
Tests were outdated after _get_and_validate_existing_key was refactored
to use prisma_client.db.litellm_verificationtoken.find_unique() and
ProxyException. Also add ProxyException handling in bulk_update_keys
error extractor so error messages aren't empty.

* fix(mcp): support refresh_token grant type in OAuth token endpoint (#23701)
* fix(mcp): support refresh_token grant type in OAuth token endpoint (#23700)
The .well-known/oauth-authorization-server metadata advertises
refresh_token as a supported grant type, but the token endpoint
rejected it with HTTP 400. This adds refresh_token grant support
so MCP clients can refresh expired tokens without re-authenticating.
* test(mcp): add tests for refresh_token grant type in OAuth token endpoint
* fix(mcp): move code_verifier guard into authorization_code branch
code_verifier is only relevant for authorization_code grants (PKCE).
Move it inside the else branch so it doesn't apply to refresh_token.
* fix(mcp): guard None client_secret and forward scope in token exchange
- Conditionally include client_secret in form data to prevent httpx
from sending the literal string "None" (applies to both
authorization_code and refresh_token branches)
- Forward optional scope parameter per RFC 6749 §6, allowing clients
to request a subset of originally-granted scopes on refresh
* fix(mcp): validate code param in authorization_code grant
Guard against None code being form-encoded as literal string "None"
by httpx, symmetric with the existing refresh_token guard.
* docs: add incident report for guardrail logging secret exposure (#24059)
Add blog post documenting the guardrail logging path exposing internal
request data (e.g. Authorization headers) in spend logs and OTEL traces.

Wrap _run_deferred_stream_guardrails initialization (UnifiedLLMGuardrails
constructor and _check_and_merge_model_level_guardrails) in try/finally
so logging always fires even if init throws. Prevents silent logging loss
on transient errors.
Move fastapi.HTTPException import from module-level to local test-function
scope. Add test_logging_fires_even_if_guardrail_init_raises to verify the
try/finally guard.
Use the merged guardrail_data dict (from _check_and_merge_model_level_guardrails)
for hook invocations in _run_deferred_stream_guardrails, instead of the original
captured_data. This ensures model-level non-default guardrails are visible to
inner should_run_guardrail re-checks inside UnifiedLLMGuardrails.
Rewrite three hand-crafted closure tests to exercise the production
_run_deferred_stream_guardrails exception-handling path. Add three new tests
that use deep-copy mocks to prove hooks receive the merged dict.
guardrail_information is None in StandardLoggingPayload because logging
fires before post-call guardrails write to metadata.
Non-streaming: wrapper_async stores a closure instead of calling
create_task immediately. The proxy fires it in a try/finally after
post_call_success_hook so the SLP is built with guardrail info.
Streaming: a closure on logging_obj is called by CSW.__anext__ at
stream end. The closure runs only guardrail hooks (not all callbacks)
on the assembled response, then fires both logging handlers. This
avoids behavioral changes for non-guardrail callbacks on streaming.
- Change `if team_limit:` to `if team_limit is not None:` in both
get_key_model_rpm_limit and get_key_model_tpm_limit so that an
explicitly-empty team rate-limit map ({}) is returned as-is instead
of silently falling through to deployment defaults (P1 fix).
- Replace the bare `int()` list comprehension in _get_deployment_default_limit
with a loop that catches ValueError/TypeError so malformed config strings
do not raise an unhandled exception during request handling (P2 fix).
- Add corresponding unit tests for both edge cases.

- Merge _get_deployment_default_rpm_limit and _get_deployment_default_tpm_limit
into a single _get_deployment_default_limit(model_name, field) helper; the two
thin wrappers are preserved for callers but share one implementation
- Compute _success_tpm_limit / _success_rpm_limit once before the guard condition
in async_log_success_event, eliminating the previous two unconditional
get_key_model_* calls (each of which could hit llm_router.get_model_list)
- Replace fragile llm_model_list=[{}] sentinel in test with []

Aligns proxy default with litellm.AZURE_DEFAULT_API_VERSION (2025-02-01-preview)
so Azure response_format + json_schema works without tools fallback.
Made-with: Cursor
Replace bare _get_deployment_default_tpm/rpm_limit calls in the
async_log_success_event condition with get_key_model_tpm/rpm_limit
(model_name=model_group). The higher-level getters short-circuit on
key/team metadata hits before ever reaching the router, so requests
that don't use deployment defaults incur no extra router lookup. Remove
the now-unused bare helper imports.
Also fix invalid `int = None` type hints in test helper signatures
to `Optional[int] = None`.

- Use min() across all matching deployments instead of first-wins when
resolving default_api_key_tpm/rpm_limit for a model group, so
load-balanced setups with different per-deployment limits always apply
the most conservative value
- Replace the global SensitiveDataMasker non_sensitive_overrides change
with a targeted excluded_keys set at the remove_sensitive_info_from_deployment
call site, avoiding unintended suppression of other fields
- Update the v1 parallel request limiter to pass model_name to
get_key_model_tpm/rpm_limit so deployment defaults apply there too
- Add 4 tests covering multi-deployment min semantics
Co-Authored-By: Claude (claude-sonnet-4-6) <noreply@anthropic.com>
Adds `default_api_key_tpm_limit` and `default_api_key_rpm_limit` to
`GenericLiteLLMParams` so operators can set per-deployment rate limit
defaults in config.yaml. When a key has no model-specific tpm/rpm limit
configured, the proxy falls back to these deployment defaults (Case 2 in
spec). Key-level limits always take priority (Case 1).
- Extends `get_key_model_tpm_limit` / `get_key_model_rpm_limit` with a
`model_name` param and a priority-4 deployment-default fallback
- Passes `model_name=requested_model` in the parallel request limiter so
the fallback is triggered at enforcement time
- Adds `"limit"` to `SensitiveDataMasker` non-sensitive overrides so
`*_limit` fields are not masked in `/model/info` responses
- Adds 17 unit tests covering both spec cases and the `/model/info` path

- Only remove wildcard path from openai_routes when the route entry has
type="subpath", avoiding accidental removal when two endpoints share
the same base path but differ in include_subpath

prevent stale entries from polluting subsequent tests on failure
- Add dedup guard for base path registration (prevents unbounded list
growth on config reload)
- Clean up base path and wildcard path from openai_routes when an
endpoint is removed via remove_endpoint_routes
- Rewrite test to exercise initialize_pass_through_endpoints directly,
covering registration, dedup on reload, and cleanup on removal
