From 381cba33eb44064c250f1b44b4c048eacc71646f Mon Sep 17 00:00:00 2001 From: mateo-berri <277851410+mateo-berri@users.noreply.github.com> Date: Wed, 28 Oct 2026 07:20:57 -0700 Subject: [PATCH 1/9] fix(guardrails): scan decision and extraction request text with native-hook guardrails Guardrails that keep their own lifecycle hooks (hide-secrets, Model Armor, Azure Prompt Shield, Azure Text Moderation, LLM Shield Proxy) read messages, input, or prompt, so they found no text on /v1/extraction and /v1/systemone and missed the question instructions on /v1/decisions. On those call types they now run through apply_guardrail, a new decisions translation scans the input or state plus each question's instructions, and a requested guardrail is no longer listed as applied unless it actually scanned. Hide-secrets keeps its per-key opt-out on the unified path --- .../enterprise_callbacks/secret_detection.py | 37 ++- litellm/integrations/custom_guardrail.py | 19 ++ .../guardrail_translation/base_translation.py | 2 + .../guardrail_translation/__init__.py | 13 + .../guardrail_translation/handler.py | 168 ++++++++++++ .../unified_guardrail/unified_guardrail.py | 6 +- .../proxy/policy_engine/pipeline_executor.py | 4 +- litellm/proxy/utils.py | 69 +++-- .../test_secret_detection.py | 41 ++- .../integrations/test_custom_guardrail.py | 38 +++ .../guardrail_translation/__init__.py | 0 .../test_decisions_guardrail_handler.py | 176 +++++++++++++ .../policy_engine/test_pipeline_executor.py | 20 ++ .../test_proxy_logging_hook_detection.py | 248 ++++++++++++++++++ .../proxy_logging/test_guardrail_pipeline.py | 8 +- .../utils/proxy_logging/test_pre_call_hook.py | 2 +- 16 files changed, 809 insertions(+), 42 deletions(-) create mode 100644 litellm/llms/openai/decisions/guardrail_translation/__init__.py create mode 100644 litellm/llms/openai/decisions/guardrail_translation/handler.py create mode 100644 tests/unit/llms/openai/decisions/guardrail_translation/__init__.py create mode 100644 tests/unit/llms/openai/decisions/guardrail_translation/test_decisions_guardrail_handler.py diff --git a/enterprise/litellm_enterprise/enterprise_callbacks/secret_detection.py b/enterprise/litellm_enterprise/enterprise_callbacks/secret_detection.py index 65e4d50587f..35c0c7dd119 100644 --- a/enterprise/litellm_enterprise/enterprise_callbacks/secret_detection.py +++ b/enterprise/litellm_enterprise/enterprise_callbacks/secret_detection.py @@ -19,7 +19,7 @@ import json import re import tempfile from collections import OrderedDict -from collections.abc import Generator, Iterator, Sequence +from collections.abc import Generator, Iterator, Mapping, Sequence from contextvars import ContextVar from functools import partial from typing import TYPE_CHECKING, ClassVar, Final, Literal, Optional @@ -600,6 +600,24 @@ def _next_run_state(budget: int, state: tuple[int, int, int], size: int) -> tupl return run_id, count + 1, total + size +_KEY_PERMISSIONS: Final[TypeAdapter[Mapping[object, object] | None]] = TypeAdapter(Mapping[object, object] | None) +_METADATA_BUCKET: Final = TypeAdapter(Mapping[str, object]) + + +def _key_opted_out(key_auth: object) -> bool: + if not isinstance(key_auth, UserAPIKeyAuth): + return False + permissions: Final = _KEY_PERMISSIONS.validate_python(key_auth.permissions) + return permissions is not None and permissions.get(GUARDRAIL_NAME) is False + + +def _request_key_opted_out(data: Mapping[str, object]) -> bool: + return any( + isinstance(bucket, dict) and _key_opted_out(_METADATA_BUCKET.validate_python(bucket).get("user_api_key_auth")) + for bucket in (data.get("metadata"), data.get("litellm_metadata")) + ) + + def _value_in_texts(value: str, texts: Sequence[str]) -> str | None: """Return the detected value as it appears in ``texts``, decoding it when it came from a JSON-escaped key line.""" candidates: Final = (value, _json_unescaped(value)) @@ -608,7 +626,7 @@ def _value_in_texts(value: str, texts: Sequence[str]) -> str | None: class _ENTERPRISE_SecretDetection(CustomGuardrail): # Keeps proxied traffic on async_pre_call_hook (the unified apply_guardrail - # path skips should_run_check and never sees data["prompt"]). + # path never sees data["prompt"]). use_native_lifecycle_hooks: ClassVar[bool] = True def __init__(self, detect_secrets_config: Optional[dict] = None, **kwargs): @@ -693,12 +711,12 @@ class _ENTERPRISE_SecretDetection(CustomGuardrail): return map_tool_json_text(payload, lambda text: pattern.sub("[REDACTED]", text)) async def should_run_check(self, user_api_key_dict: UserAPIKeyAuth) -> bool: - if user_api_key_dict.permissions is not None: - if GUARDRAIL_NAME in user_api_key_dict.permissions: - if user_api_key_dict.permissions[GUARDRAIL_NAME] is False: - return False + return not _key_opted_out(user_api_key_dict) - return True + def should_run_guardrail(self, data: Mapping[str, object], event_type: GuardrailEventHooks) -> bool: + return super().should_run_guardrail( # pyright: ignore[reportUnknownMemberType] # CustomGuardrail.should_run_guardrail leaves data untyped + data, event_type + ) and not _request_key_opted_out(data) @log_guardrail_information async def apply_guardrail( @@ -709,8 +727,9 @@ class _ENTERPRISE_SecretDetection(CustomGuardrail): logging_obj: Optional["LiteLLMLoggingObj"] = None, ) -> GenericGuardrailAPIInputs: """Unified-interface entrypoint, used by /guardrails/apply_guardrail - (the UI test playground).

text, and scan every part the model reads Decision Model, Aim, Cato Networks, and Lasso add themselves to x-litellm-applied-guardrails when they scan a request, so the decisions routes keep listing them. Aim, Cato Networks, and Pangea no longer call their API when a request has no text for them. The systemone translation scans keys and numbers in state plus criteria descriptions, and decisions scans choice and level descriptions. Model Armor honors its mask flags and fail_on_error in apply_guardrail, and Pillar, DynamoAI, and IBM Guardrails list themselves only when they had text to scan. --- .../guardrail_translation/base_translation.py | 2 + .../guardrail_translation/handler.py | 145 +++++++++++++++-- .../guardrails/guardrail_hooks/aim/aim.py | 9 +- .../cato_networks/cato_networks.py | 9 +- .../decision_model/decision_model.py | 4 + .../guardrail_hooks/dynamoai/dynamoai.py | 9 +- .../ibm_guardrails/ibm_detector.py | 9 +- .../guardrails/guardrail_hooks/lasso/lasso.py | 4 + .../model_armor/model_armor.py | 40 +++-- .../guardrail_hooks/pangea/pangea.py | 2 + .../guardrail_hooks/pillar/pillar.py | 8 +- .../unified_guardrail/unified_guardrail.py | 5 +- .../test_decisions_guardrail_handler.py | 146 +++++++++++++++--- .../guardrail_hooks/dynamoai/test_dynamoai.py | 70 +++++++++ .../ibm_guardrails/test_ibm_detector.py | 85 ++++++++++ .../guardrails/guardrail_hooks/test_aim.py | 33 +++- .../guardrail_hooks/test_cato_networks.py | 32 ++++ .../guardrail_hooks/test_decision_model.py | 23 +++ .../guardrails/guardrail_hooks/test_lasso.py | 32 ++++ .../guardrail_hooks/test_model_armor.py | 128 +++++++++++++++ .../guardrails/guardrail_hooks/test_pangea.py | 37 +++++ .../guardrails/test_pillar_guardrails.py | 50 ++++++ .../test_proxy_logging_hook_detection.py | 15 ++ 23 files changed, 832 insertions(+), 65 deletions(-) diff --git a/litellm/llms/base_llm/guardrail_translation/base_translation.py b/litellm/llms/base_llm/guardrail_translation/base_translation.py index 104c82812e9..6b044a87521 100644 --- a/litellm/llms/base_llm/guardrail_translation/base_translation.py +++ b/litellm/llms/base_llm/guardrail_translation/base_translation.py @@ -74,6 +74,8 @@ class BaseTranslation(ABC): scans_responses: ClassVar[bool] = True + lists_guardrail_when_called: ClassVar[bool] = False + def post_call_hook_response(self, response: object) -> object: """The ``response`` this endpoint's non-streaming post-call hooks receive, derived from the object the translation stores under ``request_data["response"]`` while scanning an diff --git a/litellm/llms/openai/decisions/guardrail_translation/handler.py b/litellm/llms/openai/decisions/guardrail_translation/handler.py index 0244b44f688..76032483949 100644 --- a/litellm/llms/openai/decisions/guardrail_translation/handler.py +++ b/litellm/llms/openai/decisions/guardrail_translation/handler.py @@ -1,4 +1,5 @@ -from collections.abc import Mapping +import json +from collections.abc import Iterator, Mapping from itertools import chain from types import MappingProxyType from typing import TYPE_CHECKING, ClassVar, Final @@ -6,7 +7,7 @@ from typing import TYPE_CHECKING, ClassVar, Final from pydantic import JsonValue, TypeAdapter from litellm.llms.base_llm.guardrail_translation.base_translation import BaseTranslation -from litellm.proxy.guardrails._content_utils import iter_tool_json_text, map_tool_json_text +from litellm.llms.base_llm.guardrail_translation.utils import unappliable_request_rewrite from litellm.types.utils import GenericGuardrailAPIInputs if TYPE_CHECKING: @@ -15,6 +16,7 @@ if TYPE_CHECKING: from litellm.types.proxy.auth.user_api_key_auth import UserAPIKeyAuth _JSON_ADAPTER: Final[TypeAdapter[JsonValue]] = TypeAdapter(JsonValue) +_DESCRIBED_ITEM_KEYS: Final = ("choices", "levels") _QUESTION_LIST_ADAPTER: Final[TypeAdapter[tuple[Mapping[str, JsonValue], ...]]] = TypeAdapter( tuple[Mapping[str, JsonValue], ...] ) @@ -73,20 +75,123 @@ def _guardrailed_input(decision_input: JsonValue, guardrailed: Mapping[str, str] return [_guardrailed_message(message, guardrailed) for message in decision_input] -def _guardrailed_json(value: JsonValue, guardrailed: Mapping[str, str]) -> JsonValue: -

Model Armor masking on these routes moves to a follow-up, while its fail_on_error now covers network failures too.

Every path needs curl, openssl, and python3, so ask the user to install any that is missing. The uv path needs uv, which downloads a supported Python (LiteLLM supports 3.10 to 3.14) when the `--python` range in step 4 rules out the one on the machine. If uv is missing, offer to install it, and only after the user says yes run `curl -LsSf https://astral.sh/uv/install.sh | env UV_NO_MODIFY_PATH=1 sh`, which leaves their shell profile alone (https://docs.astral.sh/uv/getting-started/installation/). It puts uv in `~/.local/bin`, so start every later command that runs `uv` or `litellm` with `export PATH="$HOME/.local/bin:$PATH";`. The Docker path needs a running Docker daemon, and the quickstart also needs Docker Compose v2. If `docker info` says `permission denied`, the user's account cannot use Docker without sudo.

Download it, then run it with the folder and port from step 1. It returns once the gateway is ready: + +```bash +curl -fsSL https://raw.githubusercontent.com/BerriAI/litellm/main/scripts/quickstart.sh -o quickstart.sh +LITELLM_DIR="$PWD/litellm-gateway" LITELLM_PORT=4000 sh quickstart.sh --yes +cd litellm-gateway +``` + +Models live in the database here, so add each one through the API instead of a `config.yaml`, naming it the way step 5 says. Pipe the request body in, so the provider key never shows up in output or on a command line. Unless the user agreed to the key in your environment, as step 5 says, ask them to add the line `OPENAI_API_KEY=` to this `.env` themselves. Run the loader line first: + +```bash +python3 -c 'import json, os, sys; json.dump({"model_name": "gpt-6.1-sol", "litellm_params": {"model": "openai/gpt-6.1-sol", "api_key": os.environ["OPENAI_API_KEY"]}}, sys.stdout)' \ + | curl -sS -o /dev/null -w '%{http_code}\n' http://127.0.0.1:4000/model/new \ + -H "Authorization: Bearer $LITELLM_MASTER_KEY" -H "Content-Type: application/json" -d @- +``` + +Run that in one shell command that starts with the loader line, since the master key is in `.env`. `200` means the model was added.

Install + +uv: + +```bash +uv tool install --python '>=3.10,<3.15' 'litellm[proxy]' +export PATH="$(uv tool dir --bin):$PATH"; litellm --version +``` + +With their own Postgres, install `'litellm[proxy,extra_proxy]'` instead, with the same `--python` range, which adds the Prisma client the proxy uses for the database. Running `uv tool install` again with the new extras replaces the old install. Start every later command that runs `litellm` with `export PATH="$(uv tool dir --bin):$PATH";`, so this install runs even when the shell has no `litellm` or an older one from a venv or `pip install litellm`. `uv tool update-shell` puts it on the PATH of new shells by editing the user's shell profile, so run it only after the user says yes + +Docker: + +```bash +docker pull docker.litellm.ai/berriai/litellm:main-stable +``` + +## 5. Write `.env` and `config.yaml` + +Run every command from here on in the folder from step 1.

Otherwise ask the user to add the line `OPENAI_API_KEY=` to `.env` themselves and tell you when it is there. If they paste a key into the chat anyway, write it to `.env` and never repeat it. Keep one `NAME=value` per line with no quotes, so `docker --env-file` and the loader line read the same value + +Confirm each model's current LiteLLM name in the cost map instead of trusting memory, since model names go stale fast. This prints the chat models of the provider named last (`openai`, `anthropic`, `gemini`, `azure`, `bedrock`, `vertex_ai`, and so on) the way `config.yaml` takes them, with the provider in front. It matches by prefix, so `bedrock` also lists the newer Bedrock models and `vertex_ai` lists every Vertex family. For Ollama, use a model from `ollama list` instead: + +```bash +curl -fsSL https://raw.githubusercontent.com/BerriAI/litellm/main/model_prices_and_context_window.json | python3 -c ' +import json, sys +for name, row in json.load(sys.stdin).items(): + provider = str(row.get("litellm_provider", "")) if isinstance(row, dict) else "" + if provider.startswith(sys.argv[1]) and row.get("mode") == "chat": + prefix = "bedrock" if provider == "bedrock_converse" else "vertex_ai" if provider.startswith("vertex_ai") else provider + print(name if name.startswith(prefix + "/") else prefix + "/" + name) +' openai +``` + +In `config.yaml`, `model` is a name from that list, as in `openai/gpt-6.1-sol` or `bedrock/us.anthropic.`, and `model_name` is what clients will send. If the folder already has a `config.yaml`, show the user its `model_name` lines and ask before replacing it. This example uses the newest GPT model in the cost map when this skill was written, so replace it with what the user picked: + +```yaml +model_list: + - model_name: gpt-6.1-sol + litellm_params: + model: openai/gpt-6.1-sol + api_key: os.environ/OPENAI_API_KEY + +general_settings: + master_key: os.environ/LITELLM_MASTER_KEY +``` + +Add one entry per model. On Azure, ask the user for each deployment's name and the model it runs. Use `azure/` as `model`, since Azure routes by deployment and a name from the lookup works only when the deployment has that same name, and add `model_info:` with `base_model: azure/` to the entry, since LiteLLM prices each call by that name. Providers that need more than a key, like Azure or Bedrock, list their `litellm_params` on their page under https://docs.litellm.ai/docs/providers. Point every secret at `.env` through `os.environ/NAME` the same way + +## 6. Their own Postgres, on the uv path + +Ask the user to create a new, empty database for LiteLLM on their server (`CREATE DATABASE litellm;`) and add `DATABASE_URL=postgresql://...` for it to `.env` themselves. The proxy creates its tables there on first start and stops on a database that already holds other tables. If that URL goes through a transaction pooler such as PgBouncer, they also add `DIRECT_URL` for the same database without the pooler, which the migrations use. Then add a salt key. It encrypts the provider credentials the proxy stores in the database and falls back to the master key when unset, so set it once and never change it: + +```bash +grep -q '^LITELLM_SALT_KEY=.' .env || printf 'LITELLM_SALT_KEY=sk-%s\n' "$(openssl rand -hex 32)" >> .env +``` + +Generate the Prisma client once inside the tool's environment.

Fix it in `.env` and restart, since the proxy reads the environment only at startup. On uv, stop it and rerun step 7. On Docker, `docker rm -f litellm` and rerun step 7, since `docker restart` keeps the environment the container was created with. On the quickstart the key is saved with the model, so delete the model and add it again: `GET /model/info` lists each model's `model_info.id`, and `POST /model/delete` with `{"id": ""}` deletes it +- `Cannot automatically baseline this database` means `DATABASE_URL` points at a database that already holds tables LiteLLM did not create.

On extraction, decisions, and systemone the guardrail step seeds litellm_metadata from metadata, so router tags, budgets, and fallbacks keep reading the request's own bucket, and /v1/decisions exposes its input as messages for image-aware routing. The applied guardrails header unions both metadata buckets, so a guardrail listed in metadata is no longer dropped when another lists itself in litellm_metadata. Azure Prompt Shield and Text Moderation go back to one Azure request per text, since joining the texts hid a prompt injection from Prompt Shield.

17 00:00:00 2001 From: mateo-berri <277851410+mateo-berri@users.noreply.github.com> Date: Thu, 29 Oct 2026 14:29:56 -0700 Subject: [PATCH 7/9] fix(guardrails): keep chat headers as before and check escaped systemone entries Vendor guardrails with their own hooks list themselves in the applied guardrails header as before on chat, Responses and Messages, and only when they scanned text on extraction and decision routes Model Armor lists itself only once its API answered, so a call it let through with fail_on_error false is no longer listed A systemone entry whose JSON escaping splits a value is scanned in its decoded form too, and a rewrite where the two forms disagree is rejected --- litellm/integrations/custom_guardrail.py | 7 +++ .../guardrail_translation/handler.py | 27

Taking only the decoded rewrite dropped a mask that needed the key, so a tax number under a TFN key reached the provider when an email in the same value was also masked. Both rewrites' edits now apply together, word by word, and a larger mask wins over a smaller one inside it. Edits that partly overlap reject the request as unappliable. The entry scan sees each letter escape followed by a tilde that is removed afterwards, so a match next to an escape no longer swallows the escape letter. --- .../guardrail_translation/handler.py | 73 +++++++++++++--- .../test_decisions_guardrail_handler.py | 83 +++++++++++++++++-- 2 files changed, 139 insertions(+), 17 deletions(-) diff --git a/litellm/llms/openai/decisions/guardrail_translation/handler.py b/litellm/llms/openai/decisions/guardrail_translation/handler.py index ead6f3e176c..5b02a037041 100644 --- a/litellm/llms/openai/decisions/guardrail_translation/handler.py +++ b/litellm/llms/openai/decisions/guardrail_translation/handler.py @@ -1,9 +1,10 @@ import json import re from collections.abc import Iterator, Mapping +from difflib import SequenceMatcher from itertools import chain, groupby from types import MappingProxyType -from typing import TYPE_CHECKING, ClassVar, Final, TypeVar +from typing import TYPE_CHECKING, ClassVar, Final from pydantic import JsonValue, TypeAdapter, ValidationError @@ -21,8 +22,10 @@ if TYPE_CHECKING: _JSON_ADAPTER: Final[TypeAdapter[JsonValue]] = TypeAdapter(JsonValue) _KEY_ADAPTER: Final[TypeAdapter[str]] = TypeAdapter(str) _JSON_KEY_PREFIX: Final = re.compile(r'("(?:[^"\\\x00-\x1f]|\\(?:["\\/bfnrt]|u[0-9a-fA-F]{4}))*"): ') +_JSON_ESCAPE: Final = re.compile(r"(\\(?:[bfnrt]|u[0-9a-fA-F]{4}))|\\.") +_MARKED_JSON_ESCAPE: Final = re.compile(r"(\\(?:[bfnrt]|u[0-9a-fA-F]{4}))~|\\.") +_TOKEN: Final = re.compile(r"\s+|\S+") _DESCRIBED_ITEM_KEYS: Final = ("choices", "levels") -_Field: Final = TypeVar("_Field", bound=JsonValue) _QUESTION_LIST_ADAPTER: Final[TypeAdapter[tuple[Mapping[str, JsonValue], ...]]] = TypeAdapter( tuple[Mapping[str, JsonValue], ...] ) @@ -81,8 +84,16 @@ def _guardrailed_input(decision_input: JsonValue, guardrailed: Mapping[str, str] return [_guardrailed_message(message, guardrailed) for message in decision_input] +def _marked_escape(escape: re.Match[str]) -> str: + return f"{escape.group()}~" if escape.group(1) else escape.group() + + +def _unmarked_escape(escape: re.Match[str]) -> str: + return escape.group(1) or escape.group() + + def _entry_text(key: str, value: str | float | None) -> str: -
