All three call authenticate_user, and none of them keeps any record of how many times a given caller has already been refused, so a misbehaving or misconfigured client can retry indefinitely at full speed. A LoginThrottle is now a required argument to authenticate_user, so the accounting lives at the one function all three endpoints share and a fourth endpoint cannot be added without deciding what to pass. Failures are counted per username and source address over a fixed window and further attempts are refused with 429 and a Retry-After header. The check runs before the database lookup and before the password comparison, so a refused caller does no further work. Only genuine credential rejections count. Configuration errors do not, a refused attempt does not extend the window, and a successful sign-in clears the bucket. The username is case folded because the user lookup is case insensitive, so casing cannot multiply the allowance. Both credential rejections now return one identical message. SSO is unaffected; it never calls this function. max_failed_login_attempts (10) and failed_login_window_seconds (900) are read from config.yaml, with LITELLM_DISABLE_LOGIN_RATE_LIMIT to turn the accounting off. They are deliberately not database backed, so editing YAML always wins and an operator refused by a bad value can recover. --- litellm/proxy/_types.py | 10 + litellm/proxy/auth/login_throttle.py | 177 +++++++ litellm/proxy/auth/login_utils.py | 18 +- litellm/proxy/proxy_server.py | 7 +- .../proxy/auth/test_login_utils.py | 477 ++++++++++++++++++ .../proxy/proxy_server/conftest.py | 25 + .../proxy_server/test_routes_login_sso.py | 92 +++- tests/test_litellm/proxy/test_proxy_server.py | 39 +- ui/litellm-dashboard/src/lib/http/schema.d.ts | 10 + 9 files changed, 843 insertions(+), 12 deletions(-) create mode 100644 litellm/proxy/auth/login_throttle.py diff --git a/litellm/proxy/_types.py b/litellm/proxy/_types.py index ed35691c6ec..1fd2781bd95 100644 --- a/litellm/proxy/_types.py +++ b/litellm/proxy/_types.py @@ -2525,6 +2525,16 @@ class ConfigGeneralSettings(LiteLLMPydanticObjectBase): description="sends alerts if requests hang for 5min+", ) ui_access_mode: Literal["admin_only", "all"] | None = Field("all", description="Control access to the Proxy UI") + max_failed_login_attempts: int | None = Field( + None, + ge=1, + description="Number of failed Admin UI sign-in attempts allowed for one username from one source address within `failed_login_window_seconds`, before further attempts are refused with 429.

Introduce AwsAuthParams, a frozen pydantic model whose fields are exactly the credential-shaped params get_credentials accepts, plus resolve_credentials on BaseAWSLLM and pop_aws_auth_params for the call sites that must strip the keys out of optional_params. Deriving AWS_AUTH_PARAM_KEYS from the model's fields means the mirror list in common_utils can no longer drift from the struct. Behavior is unchanged: the same values reach STS from the same call sites. Dropping any one field from the resolver fails one of the new tests.

Over one full week of new issues (167, 5 to 12 Sep) it flagged 2, both wrong, while hand review found 11 real duplicates that nothing caught. The new workflow fetches the issue through the API into a file, runs openai/codex-action with a fixed prompt and an output schema, and lets Codex search the tracker with gh. At a 0.95 confidence gate it would have posted 12 comments that week, 9 naming a real duplicate. It reuses the same marker comment and potential-duplicate label as before so auto-close-duplicates.yml keeps working unchanged, and warns about the auto-close only when the titles actually match. Traffic goes through LiteLLM: the key is a virtual key and the endpoint is the proxy's /v1/responses. Comments and labels stay off until the DUPLICATE_CHECK_ENABLED repo variable is set. --- .github/prompts/duplicate-issue-check.md | 51 ++++++ .../prompts/duplicate-issue-check.schema.json | 24 +++ .github/workflows/check_duplicate_issues.yml | 37 ---- .github/workflows/duplicate_issue_check.yml | 170 ++++++++++++++++++ 4 files changed, 245 insertions(+), 37 deletions(-) create mode 100644 .github/prompts/duplicate-issue-check.md create mode 100644 .github/prompts/duplicate-issue-check.schema.json delete mode 100644 .github/workflows/check_duplicate_issues.yml create mode 100644 .github/workflows/duplicate_issue_check.yml diff --git a/.github/prompts/duplicate-issue-check.md b/.github/prompts/duplicate-issue-check.md new file mode 100644 index 00000000000..97305886f1f --- /dev/null +++ b/.github/prompts/duplicate-issue-check.md @@ -0,0 +1,51 @@ +You are triaging one newly opened issue in the GitHub repository `BerriAI/litellm` and deciding whether an earlier issue already reports the same thing. + +The issue under review is in `issue.json` in your working directory, as JSON with `number`, `title`, `body`.

The router passes its stream_timeout alongside the explicit timeout. --- litellm/passthrough/timeout_utils.py | 23 ++++++-- litellm/router.py | 4 ++ .../test_pass_through_endpoints.py | 58 +++++++++++++++++++ tests/test_litellm/test_router.py | 58 +++++++++++++++++++ 4 files changed, 139 insertions(+), 4 deletions(-) diff --git a/litellm/passthrough/timeout_utils.py b/litellm/passthrough/timeout_utils.py index 39127d19183..fb649a9eeaf 100644 --- a/litellm/passthrough/timeout_utils.py +++ b/litellm/passthrough/timeout_utils.py @@ -34,22 +34,37 @@ def resolve_llm_passthrough_timeout( kwargs: dict | None = None, litellm_params: dict | None = None, router_timeout: float | None = None, + router_stream_timeout: float | None = None, ) -> float: """ - Resolve upstream httpx timeout for SDK native passthrough (e.g. Bedrock /converse). + Resolve upstream httpx timeout for SDK native passthrough (e.g. Bedrock /converse, + Anthropic /v1/messages). - Precedence: kwargs timeout/request_timeout -> litellm_params timeout/request_timeout - -> router_timeout -> general_settings.pass_through_request_timeout -> 600s default. + Non-streaming precedence: kwargs timeout/request_timeout -> litellm_params + timeout/request_timeout -> router_timeout -> general_settings.pass_through_request_timeout + -> 600s default. + + Streaming (``kwargs["stream"]`` truthy) additionally consults ``stream_timeout`` at each + level before the non-streaming key, matching ``Router._get_stream_timeout`` on the + completion route: kwargs stream_timeout -> kwargs timeout/request_timeout -> + litellm_params stream_timeout -> litellm_params timeout/request_timeout -> + router_stream_timeout -> router_timeout -> pass_through_request_timeout -> 600s.

ad8de0e1927c18d5d14c92939bbd531c54573874 Mon Sep 17 00:00:00 2001 From: yassin Date: Tue, 15 Sep 2026 23:42:19 +0000 Subject: [PATCH 057/372] fix(proxy): roll up only closed days into LiteLLM_DailyGlobalSpend and split the key-free read at the marker The write path no longer dual-writes the global table. The cron rolls up closed UTC days only, so a pod still flushing the current day can never leave the global table short. The key-free arm reads days through the marker from the global table and later days from LiteLLM_DailyUserSpend in one UNION ALL, and the marker comes from the config cache rather than a per-request database lookup.

Each has a fixed counting window (60s) and a separate block TTL (300s). Blocks are soft: a correct password still signs in, wrong passwords from a blocked key take one of 5 held slots per worker and are held 30s before a 429. Once a pair is blocked its failures stop counting against the source. The source scope runs only when trusted_proxy_ranges is set, IPv6 is grouped by /64, and per-source limits accept IP and CIDR overrides with longest-prefix matching. Redis is authoritative through one Lua script per failure, with bounded per-worker fallback when Redis raises.

The Admin UI modal blocks picking a model another group owns.

Add BaseLLMHTTPHandler.async_retrieve_file_content_streaming, an httpx stream=True path that hands the byte iterator to the provider config through the new BaseFilesConfig.transform_file_content_stream hook and closes the response on completion, early close, and HTTP error. VertexAIFilesConfig peeks at the first JSONL row: Generate Content batch output is converted to OpenAI batch format one row at a time (content-length dropped since it changes), embeddings output stays buffered so fanned-out rows can be regrouped, and anything else passes through with the upstream content-type and content-length. vertex_ai joins FILE_CONTENT_STREAMING_PROVIDERS, so the proxy returns a StreamingResponse for it while OpenAI-compatible providers and the buffered Vertex path are unchanged.

16:36:47 -0700 Subject: [PATCH 084/372] feat(a2a): reach Microsoft Foundry agents with Entra auth and versioned card discovery Foundry serves its agent card only at agentCard/v1.0, accepts only an Entra ID bearer, and defaults to a non-blocking send, so the A2A relay and the chat completions route could not use it. The relay gains an agent_card_path litellm_param plus agentCard/v1.0 as a third discovery probe, mints a bearer from flat Entra fields on the agent (tenant_id, client_id, client_secret, azure_ad_token, azure_username, azure_password, azure_scope) for https://ai.azure.com/.default, and sends it on the card fetch, message/send, message/stream, tasks/* and the chat bridge. Chat completions look the registered agent up by its provider-stripped name so its api_key and headers reach the request, tag every message with its kind, ask for a blocking send, fall back to a blocking send when the registered card says streaming: false, and fail the call on a JSON-RPC error inside a stream instead of yielding an empty one. Entra fields stay out of the chat bridge's logged parameters.

yassin Date: Thu, 17 Sep 2026 03:14:13 +0000 Subject: [PATCH 111/372] feat(passthrough): deepgram streaming /v1/listen WebSocket passthrough with duration-based cost tracking Adds authenticated /deepgram/v1/listen and /deepgram/listen WebSocket routes that resolve the Deepgram credential through the pass-through router, inject Authorization: Token upstream, default the model to nova-3 when the client passes none, and relay audio and transcript frames unchanged. The shared WebSocket relay no longer assumes the first upstream frame is JSON and forwards every frame as received, keeping the Vertex AI Live setup handling on Vertex routes only. A Deepgram logging handler bills the call on Metadata.duration, falling back to the furthest Results start + duration, at the deepgram/ per-second rate from the model cost map Resolves LIT-7937

now refused with 429 before the database lookup and password check, in place of the soft block that held wrong guesses for 30 seconds and let a correct password through. The env admin credentials and the master key typed into the login form are refused like any other credential while blocked; recovery is the master key as an API bearer token, which never goes through the sign-in path trusted_proxy_ranges: [] now means clients connect directly, so the peer address is the source and the per-source limit stays on.

Nothing waits for a slot any more, so the max_parallel_requests_queue_size and default_max_parallel_requests_queue_size settings from the earlier commits are dropped along with their proxy validation, dashboard control and generated schema entries. The rpm/tpm derivation of the cap is unchanged. Every router endpoint family now enters the slot through one _deployment_slot context, and the provider coroutine is only created once the slot is held Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> --- litellm/constants.py | 2 -

carry end_user_budget_id in its metadata. When a request through that key names a customer that does not exist yet, the key's budget is applied to the new customer from the first request and wins over the proxy-wide max_end_user_budget_id. A customer with an explicitly assigned budget keeps it. The Admin UI exposes the setting on service-account key creation and key edit, and only proxy admins may set or clear it.
